Whitehouse.gov petition to veto SOPA
I was on a conference call w/ Zoe Lofgren (CA congress woman who is on the Judiciary fighting the hell out of this bill) and a bunch of NYC tech companies last weekend and she said petitions are essentially ignored, and instead to make phone calls to your reps and directly into the capital.This isn't to say don't sign this, but if you are really concerned, the absolute bottom line is phone calls.  Anything you can do to funnel phone calls in is what counts.Edit: Let me add this, which makes it absurdly easy: http://fightforthefuture.org/
