Aggregation and Feed Readers
Gathering information from multiple web sites, typically via RSS. Aggregation lets web sites remix the information from multiple web sites, for example by republishing all the news related to a particular keyword. Any website displaying the RSS symbol can be accesses via an aggregator or feed reader



Blog
Originally short for "weblog", it is just a web page that contains entries in reverse chronological order, with the most recent entry on top. But blogging has taken off because the explosion in blogging software has turned blogging into one of the easiest ways for people to maintain a constantly updated web presence. In addition to the classic text blog, we now have photo blogs (consisting of uploaded photos), audio blogs (a.k.a. "podcasts") and video blogs (which consist of regularly uploaded video files). 

Podcast
A radio-style audio program designed to be listened to either on the web or using an audio MP3 player like an iPod. Can be listened to live or as archived recordings. Available from services like Apple iTunes, AMP and BlogTalkRadio. Content can be almost anything, from music to news to dramatic performance.

Social Bookmarking
A user-defined taxonomy system for bookmarks. Such a taxonomy is sometimes called a folksonomy and the bookmarks are referred to as tags. Unlike storing bookmarks in a folder on your computer, tagged pages are stored on the Web and can be accessed from any computer. Web sites dedicated to social bookmarking,, provide users with a place to store, categorize, annotate and share favorite Web pages and files making them a great way to discover new sites or colleagues who share your interests.



Social Networking
Social networking sites help people discover new friends or colleagues by illuminating shared interests, related skills, or a common geographic location.



Tags
Keywords that describe the content of a web site, bookmark, photo or blog post. You can assign multiple tags to the same online resource, and different people can assign different tags to the same resource. Tag-enabled web services include social bookmarking sites (like del.icio.us), photo sharing sites (like Flickr) and blog tracking sites (like Technorati). Tags provide a useful way of organizing, retrieving and discovering information.

Wiki
A collaboratively edited web page. Wikis are frequently used to allow people to write a document together, or to share reference material that lets colleagues or even members of the public contribute content.

Collaborative Documents
Online documents which can be edited by a number of people at the same time.



Image and Video Sharing
Many web 2.0 applications allow for the sharing of images, video and sound files. Some are designed specifically for this.



Microblogging
The practice of sending brief posts (140 to 200 characters) to a personal blog on a microblogging Web site. Microposts can be made public on a Web site and/or distributed to a private group of subscribers, who can read the posts online, as an instant message or as a text message.
