DokuWiki is awesome. It's super easy to set up and runs fast even on a cheap server. I like how everything is just files - nearly every part of DokuWiki can be customized with a simple text editor. And since there is no database, making and restoring backups is trivial.
mredirect is the most underrated plugin ever. I use it all the time. It's the only redirect plugin that's both easy to use and shows a “redirected from…” message like Wikipedia.
scrapbook is also really useful for making simple copy-paste templates. It's not as powerful as WikiMedia templates, but it gets the job done most of the time. I want to make some custom plugins one day for my more complicated templates…
I use a modified version of the html5video plugin to display GIFs as looping WebM videos. This saves a ton of bandwidth and makes pages with GIFs load much faster. Sadly the original plugin no longer works and also doesn't support the kind of syntax that I need.
I have also made small modifications to the default dokuwiki template, the translation plugin and the mredirect plugin. Basically just fixing bugs and changing UI text so that it sounds nicer (to me anyways).
