Thinking of using a Wiki for my course notes / design

Have finalized the choice down to

Twiki
dokuwiki
mediawiki

Twiki has a lot of support and is flat file based.
dokuwiki is also excellent, simple design and flat file based.
MediWiki is the wiki engine used for the www.wikimedia.com site. Very featured pack. But big size and requires MySQL.
