Thanks very much for those who make and keep updating wikimatrix. I am sure that reading the big table on wikipedia has no fun.

All the below are my own opinion, which in turn are based on my special requirement and vision.

Tiddlywiki

I am a long time fans of tiddlywiki, for personal use. In particular, I love the BSD license, love the pyTW adoption when planting to server. Best for wiki / javascript hackers.

But it is simple NON-solution for multi-user environment.

Mediawiki

English wikipedia ( in fact most non-Chinese language wikipedia ) helps me a lot.

The downside is trivial, mediawiki means to be public, for text only application. I cannot blame it, but would not use it.

TWiki

Good to have ACLs ( by default, when compared to other wiki software and their often outdated ACL plug-ins ). Use it for projects and internal collaboration.

Bad, very bad when you want to install it ….

tikiwiki CMS/Groupware

Lots of features, you cannot treat it as wiki only.

Sorry, I always give up for its all-in-one, tiny font-size, rather ugly styling.
A mess of dot-php files when extracted.

PBwiki

Can anyone tell me what’s the point ? Using PB in barcamp.org is … a nightmare full with 500 and 404 for me.

Pmwiki

Good, very good for its advanced table cell syntax. Installation is not hard as well.

Yet, still have to figure out how to build up the user accounts.
