Joe's Random Ramblings

Ars Technica reports that at least 18 Senators have declared their opposition to PIPA, some changed from support to opposition.
The EFF reported over 1 million emails to Congress people going through their site. Google reported 4.5 million signatures on their petition against SOPA and PIPA.
I haven't found numbers on the number of petitions/emails filed through Wikipedia, but the Wikipedia blackout was of course very important since that's what got pretty much every news outlet to report on the blackout (although often in a somewhat slanted way, not surprising with the big media companies supporting SOPA and PIPA.)
Some companies, like Facebook and Microsoft, jumped onto the bandwagon very late, but it is important that they spoke out against SOPA. The inevitable backlash from the MPAA and other media companies about the "Internet pirates" is rendered ineffective by companies like Microsoft opposing SOPA and PIPA. Microsoft is not known for piracy, and indeed, Bill Gates has a reputation dating back to the very early days of MS of fighting against piracy (see the TV documentary "Nerds 2.0" by Bob Cringely.)

Update: Ars Technica now reports that Wikipedia had reached 162 million people with their blackout website, and 8 million looked up their Congressperson through the site. And Google got 7 million signatures on its petition (an update from the 4.5m reported earlier.)
