There is already a Minecraft post on techstartu.ps, so I don't think it is only about tech startups.

I don't think splitting is the answer: http://www.youtube.com/watch?v=iS-0Az7dgRY

IMO, HN needs to have different category pages for different topics. That would fix things, I think. There is nothing wrong with the link submission process, etc.- it is just getting high traffic.

I love HN, I really do, but I like scoped discussions sometimes and I think it'd be great to have a place where we could focus in on that.
