What do you wish you had known before starting up ?
MicahWedemeyer: I really don't see the point of these very vague Ask HN posts. Surely all of this has been said before in longer, better composed blog posts.  Just read the stories that show up on HN and you'll find answers to your 10,000ft startup questions.Ask HN is very useful for specific stuff, like "please give feedback on feature X of my site" or "should I pay for service X" On the flip side, I think it's kind of pointless to ask these kind of "How do I do a startup?" questions.
