One things that has got me hooked to reading this days is thank to @steem-bounty. Because of an eye on the reward I'll have to digest many post and drop a meaningful comment. Which has also helped to rejuvenate the readers habits on Steemit.
Also, upvotring comment also works too.
Thanks a lot for your comment. You are right steem bounty is a great tool to engage interaction and also to reward people for their comments.
