BLOGS,WIKIS, RSS FEEDS & PODCASTING

A blog (or weblog) is a website in which messages are posted and displayed with the newest at the top. Like other media, blogs often focus on a particular subject, such as food, politics, or local news (http://en.wikipedia.org/wiki/Blog).

A wiki is a type of website that allows anyone visiting the site to add, remove, or otherwise edit all content, very quickly and easily, sometimes without the need for registration (http://en.wikipedia.org/wiki/Wiki).

RSS Feeds (Really Simple Syndication) allow you to automatically scan the headlines from pre-selected Web sources. If the item looks interesting from the headline - and perhaps a brief abstract - we can click to get the full article.

Podcasting (iPOD + broadCASTING) is the distribution of audio or video files, such as radio programs or music videos, over the Internet using either RSS or Atom syndication for listening on mobile devices and personal computers, http://en.wikipedia.org/wiki/Podcasting
