This is a great topic, but honestly, it almost feels like Steemit is so new yet that everyone here is still a new user along for the ride of the beginnings of Steems life.
I totally agree that tags need to be made more like subgroups rather than hashtags that are always changing, could both be incorporated somehow?
One other issue I want to raise that wasn't mentioned is the power of commenting. Right now getting rewards from commenting is damn near a waste of time. It rarely nets any reward. I have spent more time I think reading, commenting and trying to be interactive than some of my posts with little to no reward. It would go a long way for the future of Steemit I believe if we have lively interactive conversations going on in the posts, I think finding a way to incentivize the activity needs to be looked into more, and in the case of Steemit, money talks. Even if 80% went into SP instead of SD with increased rewards for commenting would be a great start. Or am I the only one feeling this? I look at most posts and it is a bunch of 0.00's in the comments, even great comments seem to go unoticed as a by product it seems.
