Here is a great little summary of the history and reason for SOPA and PIPA
did anyone block THERE website?
I believe SOPA was put on hold for now, but a few sites got shut down in the interim. . .
Here is a link that explains what SOPA is and what it means to us all. (SOPA means: Stop Online Piracy Act)
The link I supplied gives a short talk on the subject....providing a LOT of details not included in the article you linked to. The history and actual REASON behind it all. It is VERY much a way to alter the right to be "innocent until proven guilty" to "guilty, no need for proof".
