Hey, I need to set up a random wiki. Featureset isn't particularly important, something simpler than MediaWiki is preferred. The main criteria is that it should look really snazzy. Rounded corners and such. What wiki are people using these days? Thanks.
I actually got started on that site. I went through their questionnaire and it told me 53 wikis met my needs and that made for a bit of a ridiculous looking comparison matrix.
I really like the simplicity and chosen featureset of Hatta - it is version control based (Mercurial) and works really well. The author is very responsive.
"Snazzy" is quite subjective - I like the default design not to scream "I am a wiki with a gazillion fancy features you'll never use", but your milage may vary :-)
I love DokuWiki. It's really easy to set up, and doesn't even require a database. It uses flat files, which you can read even if the DokuWiki site is down. It's pretty easy to use as well.
