To be fair, there is a lot of hate on tech forums, because that is generally the attitude of most techies. "Oh, that's stupid because of X. I've seen that back when it was Y." Most people in tech appear to believe that if you think of reasons why an idea will fail, that somehow makes you smart. I've learned the opposite, that figuring out how to make idea work is what makes you smart.

That said, HN is the Mecca of all startup-wannabes. You're going to get a disproportionate amount of lashback here either for or against all-things-startup.

Like anything, if you're going to post a comment, or a product, expect a lot of dumb negative feedback and ignore the haters. Take the good negative feedback and internalize that, though.
