Tumblr is for the Elites?

It always bugs me whenever I mention Tumblr to people and my friends tell me to shush because it's supposed to be a secret or it's meant only for the elites. Forreal, people? That's ridiculous. You act like Tumblr is some sort of secret society. I even had one friend tell me to unlink my Tumblr from my Facebook because no one on Facebook should know about it. It just totally bugs me every time she tells me that she's sad I didn't unlink it.
