Well, it works.
After several months of humming and hawing, I've finally got round to putting up a personal space on the interwebs. It has been... painful in places, especially getting werc to work (yes, that's a pun, but seriously, why does werc need a REMOTE_USER CGI variable? (No, the authentication works using cookies, not HTTP Basic Auth, before you ask)). Edit: werc also derps up sending plain HTTP requests to the HTTPS port, which can result in multiple submission. I'll have to hack on werc and my nginx config to try and fix that.
Anyway, I now have somewhere I can stick random musings so that others can read them.
