Hello qvcatullus,
Welcome to the Snapzu community. :D

Here are some helpful links to get you started if you are interested:
What is Snapzu? | Frequently Asked Questions | Tribe Index

As for "what's good" it all depends on your interests. There's a genuinely handy search tool up at the top of the page in which you can search interests or topics and see if a tribe pops up. On a more general level, there's lots of good around here - when you create your first snap, really take a look at all the options on hand to give your snap depth such as sources, tags, cross posting, and the multitude of modules (links, lists, videos, etc.) that you can add to your snap.
