I guess the first step is the hardest one and you've just made it, although procrastinating never gets less tempting.
Do you already have some exact ideas in mind, some series of posts perhaps?
I've also just recently joined Steemit myself and I find the community to be really chill for the most part, however I guess you won't really be into the stuff I post about :) it's about gaming, but adding a touch of literature/philosophy there as well now
I don't have an exact plan, but I do have half a dozen ideas or so and a few drafts. As for gaming, I'm very interested, but mostly in discussing narrative, themes, and philosophical aspects. I actually have an entry in mind about FFVI, which will make it this way eventually. I'll check out your posts!
