I'll try to explain my point of view:.
The problem (that I'm facing, I'm not speaking for other mods), is that we have to make decisions regarding the noise-to-signal ratio. I don't believe that a thread such as "N900 is for real men" deserves to be in the N900 sub forum: it doesn't discuss the hardware, it doesn't discuss *anything* specific to the N900. It's just a conglomeration of sexist comments, that don't add *anything* of value *AT ALL* !!! If anyone believes that "Men DONT care about the SIZE!" "That's what she said!" "And no, she ain't got bigger balls than I do" is anywhere related to Maemo, maybe you should try to reconsider what Maemo means to you. (those are direct quotes from a thread that in the opinion of benny1967 should be in the N900 forum).
Please don't judge a book by its cover. The same rules for threads. Don't judge its "on-topicness" based solely on the thread name. If there are 3 useful posts, followed by 3 pages worth of discussion about the US Patent Office, I'm utterly sorry, but I'm tempted to just bunk the whole thing out of the window. And this is only one example. I would like to see threads that only discuss one specific subject and die out once the topic has been taken care of. Having 2 billion "me too" messages doesn't help. Having half a million "nokia sucks" posts doesn't help. Yes, moderators could spend their time splitting off-topic posts from on-topic threads, but quite frankly I'm not going to do that.
