A lot of criticism of me encountered online has been bullying, and while the environment was abusive, some good tips came thru anyhow. Anyway, though, I can handle criticism if done via a respectful environment, but the problem with those environments is that people become "too polite" and they don't give you feedback. It reminds me of restaurants I've been at which were obviously terrible, but given my kind personality, I'm highly unlikely to complain, even anonymously.
