One thing also seemingly over looked, and that might help is word of mouth. Your audience providing how and who they learned from. Like when I mention I learned how to do charts through one of your excel post. I have seen on the block chain both steem and Hive where people are a bit wary of doing a shout out, but they do work. I know because I go to peoples pages mentioned in post.
So shout outs or mentions might be something to let your audience know you don't mind them, especially if it mentions a learning experience from you. I don't know how you would incorporate that in your post or outreach efforts, but it could be something else to think about with the block chain folks.
Shout outs are awesome and a marketing tactic that works great. Even established influencers like a shout out, and really, they are the dudes we want to be sharing our content :-)
Actually its a topic I might do a post on :-)
