Not much to add, other than the simple fact that SOPA-type legislation has nothing to do with copyright protection, and everything to do with the big guys destroying the ability of the little guys to participate. They "know" (probably correctly) that such laws will never impact them. If the New York Times says it's fair use, it's fair use, if I say it's fair use, it's copyright violation. If the powers that be yank the domain names of Eschaton World Industries, there won't be much I can do. Obviously no one's going to take nytimes.com.
