Earlier quoted context omitted.
No, I think you've completely missed the point. Anytime I've had a question, I've posted here. Sure, there are other forums, boards, groups, etc that you can go to, but if you tried to bring them all together, it would get muddled and all the good hackers would leave. Kind of like digg, reddit.
The question was "What interests me is what forums / sites people on here use to discuss startups?" as I'm curious at what other mechanisms (other than this site) people use in their daily routine. It would be interesting to see if there are certain sites which stand out. For me posting too much on this site - if everyone did it - would seriously increase the noise ratio when this is primarily a.... news site
I do see your point in that regard. The key is, if you just want to discuss a startup, you need only ask the question ("is my idea good..."), etc. If you are looking for partners, just post "looking for cofounder..". What else about startups is there to discuss, besides what is posted here and what you would talk to your cofounder(s) about? Am I missing something?
