Just thought I should note that I finally settled for a sane and simple design on my website. No wiki, for managing it, just plain old php scripts edited by hand. But I do use DokuWiki for maintaining my notes. Also experimenting with some enhanchements of my own.
What I learnt from my experiments with PhpWiki
Never use a hammer to drive a loose screw!
The trouble was that I wanted a wiki for two different purposes - as a
CMS for my website, and as a means to make notes. But PhpWiki is meant for
neither - I don't know what it's specifically good for, but it certainly
didn't serve my purpose!
Finally I learnt it the hard way - if you want to get work done in a simple
way, use a simple tool! Also if you want a simple homepage with just basic info
in it, build the damn thing yourself. And again, use simple tools ... like
Personal Weblog and Gallery and DokuWiki.
