Sometimes it's fun to install stuff just because you can. I found WakkaWiki in my quest for a lightweight PHP-based Wiki implementation. I already had MySQL installed, so I got the whole thing running in short order. It's still under development but version 0.1.1 functions well now. It's got some nice refinements like access control, simple formatting codes, and hideable page comments. Plus its output doesn't look like browser-default ass. I still haven't really found a situation where a Wiki was the perfect solution, but they sure are fun to play with. Discuss
