So yes, it had an effect. Whether it'll be enough to stop SOPA and PIPA is another matter, but it had an effect, it's undeniable.
I'm actually quite impressed how Silicon Valley is lobbying against this, they're doing a pretty good job. 2 months ago it seemed like a given both bills would pass, now they're pushing for Obama to veto it.
Also, yesterday I was browsing wikipedia to look up dates about this guy: http://en.wikipedia.org/wiki/Lajos_Kossuth
And turns out, because I have NoScript installed, wikipedia was perfectly browsable. Didn't even have to use the google cache or press the escape key. Didn't even find out wikipedia was part of the black-out stunt, until I've read it in the news.
P.S. "Pipa" means "cunt" in Polish.
