It's been bugging me, too. Right now, you have to go to page 6 of the Latest Posts listings just to catch up on the last 24 hours. The first two pages don't even complete the last two hours worth of new posts! So if someone asks a question for which only a handful of people might know the answer, then unless one of that handful is monitoring the forum within hours of when the question was asked, the thread will quickly get lost in obscurity.
I don't know the solution, because almost all the threads in Latest Posts seem to be legit topics. There are a number of threads where the responses have devolved into chat, which I'm trying to lessen, but that's tricky, because declaring certain conversation to be "useless chat" is controversial. People get very touchy about it, and in many cases, seem to honestly not understand the difference, which means long conversations on my end, not to mention hurt feelings on their end.
