While it's clear SOPA isn't going anywhere, my concern is that the "next" SOPA won't be so extreme and hence, the outrage will be muted. All they need is a foothold to build off of. Luckily they were dumb this time and tried to go big.
I once read a comment regarding the content industry's push for more draconian laws regarding piracy, and that guy said, they will keep doing this until the camel's back breaks, and then all their chances to pull this off will be completely eliminated, and they might even be worse off in the end (banning of online copyright, etc).
