Thanks. I actually fixed the bug that lets Joined Date get into that state with an update last night, but unfortunately this account was created before the bug fix. I'll have to see if I can update the database manually to fix it. Nothing like hacking the data on a live production site :)
I don't just drink coffee... I inhale it. I drink about 10x more coffee than any other liquid!
Thanks for reminding me about the sort order. I could probably make this an option in your general profile settings. I'd also like to add a feature to let you specify your timezone so we can translate dates into something relevant to you (and posts don't appear to come from the future!). I'll add both of these to the backlog.
At some point in the near future, I'd like to set up some sort of voting mechanism like UserVoice so people can vote on which site features they'd like to see implemented first.
Keep the great feedback coming!
