Previously, there used to be countless DApps built on Steem like Musing.io, Tasteem.io, and several others. These increased the activity levels on the Steem blockchain and provided variety with regard to the functionality of the Steem apps. Now most of them are inactive. Traditional promotion of Steem is still critical and needs to continue, but I also believe that if varieties of amazing apps built on the Steem blockchain were available and active, they could help increase the interest of some persons and lure them to the blockchain, which in turn would make the promo endeavor slightly easier.
