I'm going to look at merging this with potwiki.vim (a vim-based personal wiki) so that you can follow wiki-links and auto-create pages etc., direct from vim. (I'm writing this incase I don't get around to it) -- Jon

Another attempt at the same thing is here: http://plasticboy.com/markdown-vim-mode/

In my tests, ikiwiki.vim works better than that one, YMMV. --Joey
