To me, the really striking feature of all these Internet debates is the inadequacy of the measures proposed, as compared to the (alleged) problem that should be sold. SOPA was (so the politicians say) created to stop counterfeit medications, in other words, somehow stop medication scammers from selling their goods in the US. So in order to stop (a nasty, but by no means major) crime, you give yourself the right to disrupt the entire Internet. Because that is the thing you obviously do, fighting real-life domestic crimes with Internet blacklisting.
So the English Wikipedia is down today. Not really down, because this would be a black day for all English-speaking schoolchildren, but not obviously accessible anymore. A bit what the Internet would be like if SOPA and PIPA will pass.
