Persistence is key. Just had this convo with another Steemian @galenkp.
There are followers and then they're are followers.
After reading this fully, and surmising that I do just about everything you mention to do.. read their blogs, interact with meaningful conversation worth, and continue to produce quality content. Sure, i may not always be that interesting to listen to, I am not some poet or literate genius.. just a guy with his free mind. So I trudge on.
Cheers to Steemit, Brah.
The best thing is a free mind. Your personal views are always going to be more interesting that regurgitating what everyone else thinks.
