I imagine most people will not want to read every single post, they will scan the titles and open just the ones that matter to them or that they think they can help. In less than 12 hours I get over a page of "unread posts" and we are still "early" in the game.
It would be great if we had a button somewhere on the page where you say "I am done with these!". Maybe is not worth ... I am just trying to figure out a way to make the page help me keep up with threads that may be interesting to me.
