Wikipedia has initiated the #WikipediaBlackOut to support the anti-SOPA campaign thing. Sure, I support it too, but if you still want to see Wikipedia, use this bookmarklet code.
Add a new bookmarklet entry and paste the following code into it. It should work fine with Google Chrome and Mozilla Firefox.
And support #StopSOPA 🙂
I’ve put this up on GitHub – download the HTML from there easily: https://gist.github.com/1631955
