There are some forums and topics where it makes sense (e.g. a theory in S&T based on knowledge we had in 2005), but I will agree that there are many instances where it seems pretty pointless.

Ditto. I'd rather not sift through ten pages just to find a topic made forty days ago so I can post in it.

Solid points, but still. If there's a topic of yours, who you don't want to be revived, because it's a project or something that has valuable posts in it, why should you repost it each time 30 days pass without a post?
