A wiki allows you to create Web pages quickly, and also allows users to freely create and edit Web page content by using a Web browser.
A Wiki page is a chunk of factual content or concrete advice that is typically limited to no more than two or three screens of information.
Create forward links to pages by using the double square brackets around a WikiWord. For example, type [[BedRoom]] to create a link to the page named BedRoom. The page does not have to exist when the forward link is created.
The easiest way to create a new Wiki page is to create a forward link to a nonexistent page.
Major versions is enabled on wiki page libraries, and therefore no amendments are lost.
Blogs are personal journals or observations that are usually maintained by one person.
Blog posts can be categorized to help users find past conversations.
To interact with a blogger, you can leave comments to a blog post.
Bloggers should moderate comments to their posts.
The wiki page library and Blog Posts list are RSS support enabled, thereby allowing users to syndicate content.
