Like Im Not Sure If Its Inside Or Outside - Tumblr Posts

Okay so like, how do I do this website? No seriously, there's a ton of cool artists and shit, and Im wanting to finally start making some things but like, does it just happen by random chance here? Like, instagram you have to have millions of kinda related tags, twitter you have to post like crazy, but nah, fuck all that, I just kinda want to start this for myself.
