I noticed the random filter got axed, probably because not many people used it. I dropped an idea about this before, but I can't find it, so I'm bringing it up again.
I think it'd be cool and super useful to have a filter right next to 'hot-recent-top' that just shows you all the posts you haven't seen since the last time you hit that new filter. We can call it 'new,' and basically, it just pulls up all the unseen posts sorted from oldest to newest.
What do you fellow stackers think?
