For more, go here and see the official stance from Livejournal. (though I do kind of wish they had blacked-out too, just so we could all see how deranged we would become without it for one day, let alone forever).
Go here to Wikipedia and see the one and only English-page visible today - Wiki's stance on SOPA and PIPA. For US citizens, this page also offers you the option of putting in your zip code and finding the information for your local representatives.
If you want a really good write-up of how these bills will kill the internet, The BFF sent me this fantastic article yesterday. If you only click one of these links I am offering you, Click This One. How SOPA and PIPA will land us all in federal-pound-me-in-the-ass prison.
Lastly, Write To Your Representatives. Wikipedia informs me that my local rep has a Twitter, so I'll be sure to point out to him how Twitter will be gone in a heartbeat.
Now I must go lie down. I have a really bad stomach ache. I hope Kevin didn't get me sick.
