Hi, I'm happy to see you posting here again!
I notice that this is largely similar to another post of the same name from last March. I went ahead and triggered upvotes anyway, because that earlier post underperformed - massively (in my opinion), but for future reference, it would be helpful to curators if you could indicate when you are reposting older content.
If you do start producing new/original content for Steem again, please feel welcome to participate in the Popular STEM community. I created that when the SteemStem and STEMGeeks moderators all jumped ship. As you can see here, Another experiment advertising Steemit on Facebook, I'm playing around with Facebook advertising to try to build an audience for that community. It would be great to have you participating there.
