Facebook

Facebook is a social networking service and website launched in February 2004, operated and privately owned by Facebook, Inc. As of January 2011, Facebook has more than 600 million active users. Users may create a personal profile, add other users as friends, and exchange messages, including automatic notifications when they update their profile. Additionally, users may join common interest user groups, organized by workplace, school or college, or other characteristics. The name of the service stems from the colloquial name for the book given to students at the start of the academic year by university administrations in the United States to help students get to know each other better. Facebook allows anyone who declares themselves to be at least 13 years old to become a registered user of the website.

Facebook was founded by Mark Zuckerberg with his college roommates and fellow computer science students Eduardo Saverin, Dustin Moskovitz and Chris Hughes. The website's membership was initially limited by the founders to Harvard students, but was expanded to other colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities before opening to high school students, and, finally, to anyone aged 13 and over, but based on ConsumersReports.org on May 2011, there are 7.5 million children under 13 with accounts, violating the site's terms.

A January 2009 Compete.com study ranked Facebook as the most used social networking service by worldwide monthly active users, followed by MySpace. Entertainment Weekly included the site on its end-of-the-decade "best-of" list, saying, "How on earth did we stalk our exes, remember our co-workers' birthdays, bug our friends, and play a rousing game of Scrabulous before Facebook?" Quantcast estimates Facebook has 135.1 million monthly unique U.S. visitors in October 2010. According to Social Media Today, in April 2010 an estimated 41.6% of the U.S. population had a Facebook account.

Instapaper

Instapaper facilitates easy reading of long text content.

We discover web content throughout the day, and sometimes, we don’t have time to read long articles right when we find them.

Instapaper allows you to easily save them for later, when you do have time, so you don’t just forget about them or skim through them.

From a personal perspective, I appreciate great writing, but I’ve become frustrated with the quick-consumption nature of many devoted blog readers. Authors are encouraged to cater to drive-by visitors hurrying through their feed readers by producing lightweight content for quick skimming.

There’s no time to sit and read anything when you’re going through 500 feed items while responding to email, chatting, and watching bad YouTube videos.

As a result, popular blogs are now full of useless “list posts” with no substance or value.

Well-written content is out there, and we do have opportunities every day to read it — just not when we’re in information-skimming, speed-overload mode. But we can all read while waiting in long lines, commuting (although please not while driving), or sitting on the goofy chairs in the shoe area and being supportive while our wives are shopping.

The times we find information aren’t always ideal for consuming it. Instapaper helps you bridge that gap.

Google Alerts

Google Alerts is a content monitoring service, offered by the search engine company Google, that automatically notifies users when new content from news, web, blogs, video and/or discussion groups matches a set of search terms selected by the user and stored by the Google Alerts service. Notifications can be sent by email, as a web feed or displayed on the users iGoogle page.

Google Alerts only provides content from Google's own search engine.

Currently there are six types of alerts sent when new content matches the search terms of the alert:

Everything - aggregates News, Web and Blogs
News - sent when matching content makes it into the top ten results of a Google News search
Web - sent when new web pages appear in the top twenty results for a Google Web search
Blogs - sent when matching content appears in the top ten results of a Google Blog Search
Video - sent when matching content appears in the top ten results of a Google video search
Groups - sent when matching content appears in the top fifty results of a Google Groups search
Users determine the frequency of checks for new results. Three options are available: "once a day", "once a week", or "as it happens". These options set the maximum frequency of alerts and do not necessarily control how often they will receive alerts. Alerts are sent only if new content matches the user-selected search terms.

The first option, for example, means they will receive at most one alert email per day. The "as it happens" option can result in many alert emails per day, depending on the search.

Google Alerts are available in plain text as well as HTML. In October 2008 Google also made alerts available as RSS feeds.

Google Reader

Google Reader is a Web-based aggregator, capable of reading Atom and RSS feeds online or offline. It was released by Google on October 7, 2005 through Google Labs. Reader was graduated from beta status on September 17, 2007.

Google made major revisions to Reader's user-interface on September 28, 2006. Product manager Nick Baum described the redesign as a movement toward making news aggregation something for the general public to enjoy. Kevin Fox, the designer of the revised Google Reader, noted that the original version was optimal for those who want to read a "river" of news. The new version took into account that most readers segment their reading by feed, group, tag, folder, or into "must read" and "maybe if I get to it" feeds.

Features of Google Reader as of 2010 include:

a front page that lets you see new items at a glance
import and export subscription lists as an OPML file
keyboard shortcuts for main functions
choice between list view or expanded view for item viewing (showing either just the story title or including a description, respectively)
automatic marking of items as read as they are scrolled past (expanded view only)
search in all feeds, across all updates from subscriptions

Xanga

Xanga is a website that hosts weblogs, photoblogs, and social networking profiles. It is operated by Xanga.com, Inc., based in New York City.

Xanga's origins can be traced back to 1998, when it began as a site for sharing book and music reviews. As of April 17, 2011, Alexa Internet ranked Xanga as the 2,450th most visited site on the Internet.

All Xanga members receive a "Xanga Site", a web site made up of a weblog, a photoblog, a videoblog, an audioblog, a "Pulse" (mini-blog), and a social networking profile. Members also have the option of joining or making blogrings (groups).

Xanga first added weblogs to all Xanga Sites on November 5, 2000. Comments were added soon after, on December 8, 2000, along with the concept of "eProps", which a user can give to another user's entry as a sign of how much he or she has enjoyed the entry. Two "eProps" is the maximum amount that can be given. (By default, "2 eProps" is selected on the comment page.) Kevin Lu of Edison holds the world record for most props on a post. Comment Tracking followed on January 18, 2001.

A core part of Xanga is the ability to subscribe to other Xangas. Subscriptions allow Xangans to stay up-to-date on other Xangas to whom they are "subscribed", without needing to manually visit each site. Xanga first added an email subscriptions feature on November 30, 2000. In January 2001, this was followed by the ability to subscribe to a site using a web-based reader using RSS (and the ability to display subscriptions on one's site).

Initially, Xanga allowed members to subscribe to each others' sites anonymously. Some users were troubled by anonymous subscriptions, and so during the week of July 15, 2003, support for this feature was discontinued. Since some users had been using anonymous subscriptions to try out subscriptions to other sites, on July 21, 2003, Xanga added a feature that allows members to sample a Trial Subscription to another site. This update also allowed members to hide individual subscriptions from public display.

Subscriptions were originally called "Sites I Read", so some older users sometimes refer to them as "SIR".

LiveJournal

LiveJournal (LJ) is a virtual community where Internet users can keep a blog, journal or diary. LiveJournal is also the name of the free and open source server software that was designed to run the LiveJournal virtual community. LiveJournal's blogging features include those found in similar blogging sites (multiple authors, commenting, calendars, and polls). However, LiveJournal differentiates itself from other blogging sites by its WELL-like features of a self-contained community and some social networking features similar to other social networking sites.

LiveJournal was started on April 15, 1999 by Brad Fitzpatrick as a way of keeping his high school friends updated on his activities. In January 2005, blogging software company Six Apart purchased Danga Interactive, the company that operated LiveJournal, from Fitzpatrick.

On December 2, 2007, Six Apart announced it was selling LiveJournal to SUP, a Russian media company that had been licensing the LiveJournal brand and software for use in Russia. The new owners unveiled a plan to upgrade the service, engage with the LiveJournal community and launch new products for advertisers. This work would be undertaken by the newly formed American-based company LiveJournal, Inc.

On January 6, 2009, it was announced that LiveJournal had laid off some of their San Francisco-based employees and moved product development and design functions to Russia.

On April 22, 2009, Russian president Dmitry Medvedev opened his own blog on the LiveJournal service.

Blogger

Blogger is a blog-publishing service that allows private or multi-user blogs with time-stamped entries. It was created by Pyra Labs, which was bought by Google in 2003. Generally, the blogs are hosted by Google at a subdomain of blogspot.com. Up until May 1, 2010 Blogger allowed users to publish blogs on other hosts, via FTP. All such blogs had (or still have) to be moved to Google's own servers, with domains other than blogspot.com allowed via Custom URLs.

identi.ca

identi.ca is an open source social networking and micro-blogging service. Based on StatusNet, a micro-blogging software package built on the OpenMicroBlogging specification, Identi.ca allows users to send text updates (known as "notices") up to 140 characters long. While similar to Twitter in both concept and operation, Identi.ca provides many features not currently implemented by Twitter, including XMPP support and personal tag clouds. In addition, Identi.ca allows free export and exchange of personal and "friend" data based on the FOAF standard; therefore, notices can be fed into a Twitter account or other service, and also ported in to a private system similar to Yammer.

The service received more than 8,000 registrations and 19,000 updates within the first 24 hours of publicly launching on July 1, 2008, and reached its 1,000,000th notice on November 4, 2008. In January 2009, identi.ca received investment funds from a Montreal-based venture capital group.

On March 30, 2009 Control Yourself (since renamed StatusNet Inc) announced that Identi.ca was to become part of a hosted microblogging service called status.net to be launched in May 2009. Status.net offers individual microblogs under a subdomain to be chosen by the customer. Identi.ca will remain a free service. All notices will be published under the Creative Commons Attribution 3.0 license by default, but paying customers will be free to choose a different license.

Tumblr

Tumblr, sometimes styled as tumblr., is a microblogging platform that allows users to post text, images, videos, links, quotes and audio to their tumblelog, a short-form blog. Users can follow other users, or choose to make their tumblelog private. The service emphasizes ease of use.
