UTF-8: (in progress)
Waiting for avva to give me the okay, then we'll flip the switch and make it live, then 3,000 Russians will find bugs and get angry with avva but he'll fix them all and everything will be good.
S2: (in progress)
mart and I have been going crazy on S2 the past few days. Everytime I start working on it again I love how cool it is. And we're so close, so I want to get this bitch finished and live, then mart will take over, writing docs and guiding the masses to make tons of new styles and themes.
Site translation: (blocked on UTF-8)
I want to start removing all English strings of text from the code and replace them with resource files for different languages. I did this with FreeVote.com years and years ago, and we had that site all in 11 different languages. But UTF-8 wasn't around then (or at least not popular), so there were tons of ugly charset problems. Once UTF-8 goes live, I'm incredibly excited about making LiveJournal available in a gazillion different languages, starting with German with translation from calliste and tigerentchen. Avva will do Russian and Hebrew, probably.
XML/RSS/Syndication: (blocked on UTF-8)
Once everything goes UTF-8, then we can do XML correctly and I won't be ashamed of our broken RSS support and we can start doing more with it and promoting it more, and also do the opposite too: sucking other people's RSS into LiveJournal, so you can add RSS feeds to your friends list. (maybe somebody can find my old lj_dev post about this and I'll link it)
Trust system: dead
feh. lost interest. and everybody either 1) freaked, or 2) didn't understand it, so screw it. avva's just going to implement screened/moderated comments and community posts instead.
I really want to work on the Event/Subscription/Notification system too. That's pretty easy. Just need some time. Have a lot now, too.
Setup all the DB tables for 3 classes of user journal statistics. Just need to implement it now. Easy, also.
