Welcome to Steemit! Hope to see some great content from you, specially bjj, mma, and fitness. Steemit tends to be very anarchist, libertarian for the most part, but there are people from all political backgrounds. Feel free to post and discuss what you like. You'll find that it stays pretty tame and respectful compared to traditional social media. There is the downvote that affects people's ability to earn, so there is financial incentive to keep things respectful during discussions or debates.
Check out steemitbjj.com for more info about the Steemit ecosystem and of course ask any questions you like. We have a growing bjj/mma community here. #steemitbjj
I actually had an MMA blog so it'll be nice to get back to that I think. I wrote an article on scoring in particular that I am fairly proud of so I might copy/paste it over to here. I also wrote an ebook on getting through the white belt level of bjj and I may put that up. I think I am pretty close to finished on my writing on getting through the blue belt level as well.
Awesome!
