the thing is all the sites doing this "we're going to make the site useless to protest this crap" aren't going to get everyone signing e-petitions or contacting anyone in congress it's just going to annoy them
they just want to quickly check something on wikipedia and they're not going to stop and read the message and put in their zip code their going to just look elsewhere for the info while cursing wikipedia for wasting their time
plus if they REALLY wanted to anger people into action with this they should have got facebook, twitter, and google (with exceptions to gmail, docs, calendar, etc... shut down the search and + for a day) MS and sony should shut down Live and PSN for a day netflix, vudu, hulu... (all the paid services obviously should compensate everyone for the lost day)
so far i've only run into 3 of the "thousands" of sites and only one of them i actually use frequently which happens to be rage3d
eat right, exercise, die anyway
