Welcome to Steem!
You have to find your favorite window to interact with Steem, almost sure you're using Steemit, right? I recommend trying SteemPeak to your everyday moves around, you can upload videos to D.Tube, you can listening to music and even win money by upvoting good music at Dsound.audio.
