The variety of dApps that are being developed for STEEM is amazing. And the way the rewards are interchangeable is one of the keys. You can blog on @esteemapp @busy , @steempeak etc and earn Steem SBD to buy @steemmonster cards and play the game or even sell them on thieir market place and use the STEEM to play @magicdice, record the game and post a tutorial on @Dtube and so much more.
Once Steemians get comfortable using multiple DApps to interact with the STEEM blockchain we are really going to see an increase in adaption, engagement and innovation.
