Wedbush Securities’ Michael Pachter slammed the social networking guru for donning his trademark casual threads during talks with potential investors.

He said, “He’s actually showing investors he doesn’t care that much; he’s going to be him. I think that’s a mark of immaturity. I think he has to realise he’s bringing investors in as a new constituency right now. And he’s got to show them the respect they deserve because he’s asking them for their money.”
