You do realize there are many businesses that use Facebook? There isn't just a loss for Facebook but businesses/users as well. They are just leaving themselves out there to be sued then. I have a feeling that's why Google didn't blackout either. Although I think blacking out Google services would be a lot worse than blacking out Facebook given everything Google offers.

Either way, it worked. A lot of my non-techie friends on Facebook know about SOPA/PIPA now because of the Zuckerberg post and other people posting. In fact, them staying open probably helped out a lot, as people were able to explain numerous times what was going on. Before yesterday, they didn't.

However, I do think they could of gone the route of Google and on their login page blackout their logo and give a link or explanation right there on what's going on.

Facebook and Twitter are excellent platforms to spread the word. Shutting them down would have unintentionally undermined the efforts put about by Wikipedia and other sites. I can guarantee that a lot of my friends who were not aware of the situation, are now strong supporters of the idea. They know now because of the news spiraling down the social grapevines.

I think though a blacked out logo linking to Mark's message would have been exceptional though, because with almost a billion users, I'm pretty sure a lot would have seen it and added to the support.
