Wikipedia has officially gone dark today as a sign of solidarity against SOPA. Google is also sporting a blackout bar. Reddit, Boingboing, and a few others are standing up as well. Wikipedia is in the top ten Alexa sites and so it going dark for 24 hours should be interesting. I am sure there are some out there who won’t know what SOPA is and try to look it up on Wikipedia. That my friends is a frustrating loop.
