That is how webcomic entrepreneur The Oatmeal is participating in the Internet Blackout.

Have you been under a rock? The Internet, a huge chunk of it, is going dark today in effort to fight SOPA and PIPA. We, in contrast, are stepping out from our recent silence to tell you about the darkness. Our ways are strange and not to be questioned.

Popvox is a site recently brought to our attention that “bridges the gap between the input the public wants to provide and the information Members of Congress want and need to receive.” If we’re reading that right, Popvox is the medium for the Internet to get its voice heard in Congress.

Here are direct links to the SOPA and PIPA entries:

• The STOP Online Piracy Act (SOPA)
• The PROTECT IP Act (PIPA)

Reddit.com is another site that is planning to participate. Click the respective links to see what Redditors are saying(when the blackout is over) about SOPA and PIPA.

Below we have provided a screenshot list of sites that have already gone dark(as of this writing.):

As many as 7,000 websites are participating today in protests of some form or another against the U.S. House Of Representatives’ Stop Online Piracy Act and the U.S. Senate’s companion Protect IP Act. Some are going dark. Others are calling attention to the issue in less dramatic ways. Among the more prominent are Wikipedia, Google, Reddit, WordPress, TwitPic, Cheezburger, BoingBoing, several gaming companies including Minecraft, and Mozilla, source of the Firefox web browser. Wikipedia, BoingBoing and Minecraft have gone dark. Others, like Google, are displaying home page illustrations or visual statements about censorship and urging visitors to contact their elected representatives.

“Why is it that when Republicans and Democrats need to solve the budget and the deficit, there’s deadlock, but when Hollywood lobbyists pay them $94 million dollars to write legislation, people from both sides of the aisle line up to co-sponsor it?”
–Reddit Founder Alexis Ohanian on CNBC.

Young Master Wheaton of the Internet Hordes wrote a lovely essay on why SOPA and PIPA damage the internet.
