If you click "Learn More," you will read about the huge discourse and awareness about the bills shared to the representatives, on social media, etc., (See: #SOPA on Twitter) and the impact the bills may have, if passed.
This inconveniences web users who in turn, learn about SOPA and PIPA and then, it seems, speak out against it, which is kind of cool. It's also a wise move for Wikipedia, I think, because they are proving that they understand the impact disabling information sharing can have. It's also a good PR move for the online encyclopedia because it is showing the public that it strongly values the freedom and openness of the internet.
Do you think the Wikipedia blackout and online pressure from the public will influence the United States House of Representatives and the Senate's decision on the bill?
