I've started on a project to turn some portion of my brain into a wiki. This was, in part, inspired by my friend Mike's use of wiki as a repository for RPG knowledge. I intend to use it to store all sorts of info, though. Snippets of Perl, regular expressions, writing notes (e.g. story ideas, characters, locations), hobby notes (e.g. that shit I can never remember about camera lenses), gaming data, todo lists (to a degree), whatever. No real reason to limit the topics. Although, I suppose I will omit banking and investment info. heh.
(The side benefit is, it keeps the wiki codes in my brain so I can remember them easier when I edit a wiki at work or for the rare occasion when I edit Wikipedia.)
Perhaps I can avoid The Problem With Wikipedia.
