Why bother with tumblarity in the first place? It goes down the more original posts you make, but inflates the more generally-accepted/reblogged you become. Want high tumblarity, post pictures of squirrels doing cute things, Arcade Fire lyrics over a blurry cityscape or a picture of some pornstar wearing clothes (for once).
Fuck. That.
Everyone reposts the Little Miss Sunshine quote, Life is just one beauty pageant after another. Well, tumblarity is the same thing, and copying the same semi-idyllic post to which you appreciate the sentiment but oppose in action is retarded.
It’s your blog, kiddo. You post what you want, and nothing else. It’s a big ol’ tumblr, and there’ll always be people who like what you have to say. Just maybe not as much as they like kittens.
