SOPA being shelved isn't a decisive victory.
These things are still around, still waiting to be pushed through when we aren't paying attention and as someone stated earlier there will be others like them.
The MPAA and such will try again and again to pass these types of legislation.
DO NOT become complacent or believe we have won. We haven't.
If they try the same thing with different packaging, the same opponents will come together against it. But until that happens, we can all breathe a sigh of relief and go back to gaming and making bad arrow to the knee jokes. :P
