What’s the Difference between Announcements, Blogs, Discussions, Wikis?

Alternate Title: Battling Collaboration Memes

As mentioned previously, we are trying out SharePoint where I work, and I’m finding it interesting, maintaing 3+ blogs, including this one.

Lot’s of details and stories to write about, but one key learning we’ve captured recently …

With the SharePoint toolset, we can set up Announcements, Blogs, Discussion Forums (Fora?), and Wikis – sometimes all on the same site! If you think a bit, there’s can be very little difference between the entries on each of these lists. So, why the apparent repetition? What is the difference?

Use an Announcements to make a statement, inform of an event, where you expect no comments or replies. The flow of information is in one direction only – out from you to the readers of the web page.
