Welcome! Just off the top of my head I can think of a few places where you might find some more things to get involved in on Steemit. There's @isleofwrite and @moneyinfant's list of writing contests depending on whether you want to mingle, share or earn some Steem. The @steemartists is relatively new and very active, you'll have fun getting to know all the great artists from all around the world.

But for someone who has an interest in a bit of everything this place just feels like a playground!
