Welcome to Steemit, Fidge! :)
The cool thing is, there really isn't anything you "should" do. Just create content, video @dtube - music @dsound if you want to try another UI look at @busy.org - and if you are not a content creator, try out @steemmonsters if you're into competitive card games. If you need help with anything just tag me @theycallmedan and I will try my best to help. Cheers!
