Choosing a Wiki Services

There are a couple of big and complicated matrices and comparison charts for software and web-based wiki services. But for educational purpose the four easiest and most popular web services are:

http://sites.google.com/

http://pbwiki.com/academic.wiki


http://www.wetpaint.com/


http://www.wikispaces.com/

I personally prefer google sites since I am a big fan of all of google's services and sites allows you to mashup and combine all into it's wiki.
