New to steemit

I'm very interested in the idea of decentralization. I'm a big fan of cryptocurrency and smaller government. I'm not an anarchist or anything, but I think the lack of privacy and independence in our modern world is dangerous. Too many government organizations and private corporations have their hands on our personal information. I'm new to this site and I'm unsure what things are possible with Steemit, so I would appreciate some guidance. I know about Dtube and Dmania but I'm unfamiliar with much else about this site/organization. Any help would be appreciated.
