The best-known of the protests today, Wikipedia went completely black. It wasn't impossible to access--Google around if you want to figure out how to overcome the block--but it's arguably the most major resource that was unavailable for the day. The only pages you could access? SOPA and PIPA.

Our friends over at BoingBoing have been hammering out stories condemning SOPA and PIPA for weeks now. No surprise, then, that they  also participated in the blackout. BoingBoing went completely offline Wednesday.

The internet's main source of memes, crowd-sourced interviews with semi-confused celebrities, and also pictures of cute animals also went down Wednesday. Curiously, Reddit was only down for 12 hours, rather than the standard 24.

Tumblr's protest was one of the coolest we've seen: when Tumblr users signed into their dashboard , they had the option to check a box that would black out their Tumblr all day. Services like Tumblr and Wordpress (keep reading, it's coming!) have the power to affect thousands of individual sites.

Google didn't go dark. That'd be sort of a nuclear option for what might be the most important and most-used service online. But they did show their support in a few ways. Eric Schmidt has blasted the bills, and Google itself put a black "censored" banner over their own logo. What we really liked about Google's protest is how subtle it was. They also revealed that they reconfigured the Googlebot to crawl the web at a much lower rate for the 24 hours, which helped those sites that have gone black from losing too much traffic and SEO ratings.

No, never mind. This is the nuclear option. Cute Overload, the internet's source for all things adorable, went down Wednesday. If this doesn't help kill those bills, Congress is even more heartless than we thought.

Wired didn't go black--their protest was more aesthetic, sort of like Google's. Their front page was black-bar-censored, though the bars disappear on a mouse hover and the links all still work. But it's a really nicely jarring effect.

Wordpress's homepage usually shows some highlights of sites that use the Wordpress blogging platform, one of the most flexible and powerful platforms that's still usable by normal folks. Instead, they were all censored. It's one of the more powerful examples we've seen--this is what the world could really look like if these bills pass.

The Internet Archive, one of the most useful tools in an advanced internet browser's arsenal, also went black for 12 hours, like Reddit.

The EFF is the internet's go-to source for legal advice and assistance when attacked by external forces, so it's no surprise that they're right out on the front lines in the battle against SOPA and PIPA. The EFF's homepage had a new skin, with a nice flashlight effect and many many links to places where your voice could be heard.

American boutique publisher of many great things McSweeney's joined the SOPA protest, sort of. McSweeneys.net, the publishing company's website of short fiction and other writings, had a piece by US magazine and book writer Ben Greenman on SOPA entitled "A Day's Worth of Facts to Get You Through Wikipedia's 24-Hour Blackout." It is very funny, as are most things he writes.
