What is SOPA?
SOPA, which stands for the Stop Online Piracy Act, is a piece of legislation in the U.S. House of Representatives. The act is designed to target copyright infringers online through a series of harsh penalties.
In the U.S. Senate, a separate companion bill is called the Protect Intellectual Property Act or PIPA.
Several sites held a blackout today as seen here with WIKI
(wait, did I just pirate that Wiki blackout pic?)
Even my beloved Flickr had a blackout option and I logged in today to see my top pick already blacked out along with others of friends with an option to bypass this and see the pics anyway. It was just there to raise awareness of this issue.
The Second Life Newser seems to have the latest on this issue and implications for SL here: http://slnewser.blogspot.com/2012/01/sopa-down-but-not-dead-pipa-still-up-in.html or direct link here: SLNewserSOPAHere.
