Matt Cutts has a great summary of what's happening with SOPA: Progress against SOPA:
He has a list of things you can do:
- Sign up at American Censorship to send a note to Congress and get updates.
- Call your congressperson with Tumblr’s easy web page.
- I believe anyone inside or outside the United States can sign this White House petition. If you’re outside the United States, you can also sign this petition.
- Follow groups like the Electronic Frontier Foundation (EFF) on Twitter.
- Sign up with United Republic, a new organization dedicated to the larger problem of money in politics.
- Sign up to have Senator Ron Wyden read your name on the Senate floor when he filibusters against this legislation.
