I'm an ex-redditor, but lemme give you a piece of advice anyway: just stop thinking of "old Snapzu users" and "ex-redditors."

Reddit (and Snapzu) are just websites you visit. This site has its own feel and culture, sure, but stop behaving like you have a different group identity for coming from reddit. You're a Snapzu user.

The advice then becomes very simple: just pay attention to the way the site functions until you got a good feel for it.

That and, don't be a jerk.

Pretty easy.
