This is a really nice design but it's missing an important opportunity to convert what will initially be shock and irritation into sympathy and action.

When sites go dark, what remains will be the difference between the country getting behind the internet companies and hating them for causing disruption.

The blackout page needs to do three things:

1) making people understand the SOPA proponents made the site go dark (and not Reddit etc.)

2) make people understand just one thing about why SOPA is dangerous

3) make people take some form of action to help prevent SOPA (sign a petition etc.)

It's tough but it also has to do all of this in about 20s while people landing on it reel from the shock that Reddit / Twitter / Tumblr etc. have gone.
