I hear you. I could go on about how pop culture is lame etc and not really answer your question but I think, the more the merrier. If I'm not interested in the Lakers, I can ignore it and scroll past it. Easy. It would be nice for people who want to discuss the Lakers to have a place to discuss the Lakers, though.
Honestly this place is starting to piss me off a little bit sometimes. Because it's like the users here actually want 'All' to just be politics all the time and for there to be no variety to anything. You can talk about missing features from Reddit and think of ideas to make this place a little better and you'll get responses like "No. Why would anyone want more features? I know that I don't have to personally use them if I don't like them but I prefer pretending it's 1998, so no one can have them. And why would we want more users? I like empty communities with no activity. And then complaining about empty communities with no activity."
So I dunno. It's gonna be interesting to see if this place actually grows or if it just stagnates. I'm right there with you though. I'd be more than happy to see pop and sports and things I'm not really interested in because then there's a bigger chance of things that I am actually interested in taking off here.
