I've noticed that many people around are concerned with the idea that often all the recent posts are the ones from tavern and they are useless for them.

hmm,what about displaying newests posts in categories ?
kinda like

NEWEST POSTS :
1.discussions
- blah,blah,blah
- stuff
2.general
- junk
- spam
3.announcements
- news
- ads

I think it could help some 'anti-spammers' to chill a bit..
