I like Debian.
On one of my systems at home:
edited /etc/apt/sources.list
apt-get update
apt-get dist-upgrade
answered some questions
apt-get install phpwiki
play with phpwiki a bit. find that it isn't just what I wanted
dpkg --purge phpwiki
apt-get install twiki
play with twiki a bit. find that it should do nicely.
Now all I have to do is setup a server at work.
Oh, and used deborphaner to cleanly remove some no longer needed packages.
It doesn't get any easier than this.
