The reason I don't like them is not because of the content, it's because they almost always end up as an argument, and as much as I like this place, I'll be damned if I'm going to spend all my time on it trying to keep a lid on those threads.
Even if it doesn't turn into an argument merely because it's FS3, I then have all the *****ing about what is 'Canon' and therefore applicable to FS3, and everyone argues about weapons and ships, let alone the story itself.
It's not that I'm anti FS3, it's just that I'm of the opinion that until we are told something one way or the other, we are not going to co-erce information out of any developer, regardless of who it is, it'd be like bugging Lionhead to reform Bullfrog so we can get a Dungeon Keeper 3, even if they were planning to do so, they wouldn't share that information with people who aren't directly involved with it until they were ready.
Personally, I think that the energy being used to discuss FS3 could be put to far better use.
