I seem to mention this for all related note-taking time, but I use Noteself, an 'extension' of tiddlywiki to use a local in-browser tiddlypouch database which has the option of being synchronised to a couchdb back-end which, in my case, I self-host. This gives me 'anywhere on the internet' access to my notes. I can also save a single, local html file containing the entirety of said notes which is handy for distributed, ad-hoc backups. Featherwiki was recently on the front page, which doesn't have the maturity of tiddlywiki, but has potential.
