I agree with you about there being a lot more 'pointless' threads in the sense that they all pretty much ask the same thing, so you're having to repeat yourself a bit. I personally think the BB7 forum now should focus on what the housemates are doing at the moment, since we already know now who's won, who was evicted when, and so commenting on them constantly does get a bit tedious.
But the thing is though, no matter how much attention you draw to it, that's what a forum's about really; different types of people discussing whatever they feel like talking about in a certain topic.
