Still figuring out what to do here...

Is it like facebook? Do I just mindlessly shoot my mouth off and do whatever?
How does steemit work? I'm not much of a "blogger"... my posts are too short for blogs, but too long for tweets. I never know how "occult memes" are going to go over with a web community, some places really frown on humor keeping their spirituality very serious.
all these considerations and more.
Perhaps I need to branch out into something more mainstream, but what? I have no idea.
