Our view at deviantART regarding SOPA is that it's probably a bad idea. There should be better ways to deal with mass infringement on the Internet than this. This bill in our view can be seen as a threat to the open Internet itself and this is very hard to digest or support.
I personally have found information at the EFF and at Public Knowledge to be very helpful in understanding what is at stake.
