Considering that the point of the blackout is to raise attention, hiding is already enough. Anyone who gets to the content will be aware of the SOPA this way. I guess anyone can just use non-US proxy to get to the content anyway.

non-US proxy doesn't do the trick. The en.wikipedia.org pages are blacked out. I'm from Macedonia and when browsing the English pages get the blackout page too.

You seem to be right, I only checked the main-page and Finnish pages and they were open, so I thought all of them were.

I'm sure there will be many non-US people wondering why their page is blocked just because there is some upcoming law in the US. Its not like they can pick up the phone and call their representative to affect the matter in any way.
