That's a hard one to consciously articulate. Just pay attention to the way the site works, and make a conscious effort of fitting in. You'll figure out the unspoken rules eventually... It's how we all assimilate into new groups.

There's one we're still hashing out where you're not supposed to post multiple snaps from different sources on the same topic in the same day. If you do it'll get tagged as a "repost" even though the source is different.

I disagree with this rule for several reasons, not the least of which being I do not and never have followed whatever's trendy but instead focused on what's new. Consequently I miss a lot of trends. But since Snapzu allows us to add related links to someone else's snaps not only is it possible to add your source onto whatever someone else has already posted when people make the mistake of "reposting" this way it's easy to link the snaps together via related links. I'm hoping they'll be able to use that as a signal to voluntarily merge those snaps.
