To my followers: EVERY SINGLE ONE OF YOU NEEDS TO READ THIS ARTICLE. Then you should call/email/send carrier pigeon to your congress person. This is serious stuff. If this passes the Internet would become significantly worse.
p.s. I would expect Tumblr to die near instantaneously if it passed. So if for no other reason than your love/use of Tumblr contact your congress persons ASAP.
p.p.s. Spread the word.
