I guess you are more adventurous than I am. I have read before the stuffs you mentioned but I never had the chance to check out what are they about. I was probably more focused here. There's lot to explore. I myself think that I haven't even scratched the surface that's why I try to engage as many as I can to others. That's also to say that I'd like to connect to more people who are actively participating in the community.
Hope you find your way and get to see how much you could do as a blogger here in the Hive Blockchain. There are are other front end platform aside from ecency, but I would highly recommend ecency to you.
I still don't understand these "front-end" platforms and why I would l choose ecency over another, but I'll leave those questions for another day.
