Hallo,
I use dokuwiki on my VPS for about 2 years.
I use it in single-user-mode.
Since then I use it mainly for technical documentations (e.g. "how to set up dokuwiki"). Also there are some lists, that I use to fall back to and to store recipes.
And since last weekend I also manage my start-page there, so I can edit it easily and can excess it from all my devices.
It goes very well with my self-hosted owncloud, which I use to sync file between all my devices.
greetings,
wotanii
