Uh - this one does, and has been quite successful at it. You're entitled to your opinion, but I see nothing special in your linked site there; looks like every other forum I've seen. Instead of paging through pages to go back two days, I have to page through pages (sometimes more than ten, in my experience with other sites) to find the quoted post to get some context on it. Not superior in my book. But go with what you like.
