The time delay in implementation of the black-out on my system (via JavaScript) probably helps make the point more. I went to the main page (the link here) not by following the link from this thread, but from my browser history. I saw a brief glimpse of today's main page, and then the screen image changed to Wikipedia's black-out page. I went to the information page, and there it still shows all the headings a Wikipedian will see when logged in: the user's own user page, and user talk page, and so on. So I followed the link to my user page, and it too displayed for the briefest tantalizing moment before showing the black-out page. Slick. I tried some other stored URLs from my browser history, and they all briefly displayed the appropriate Wikipedia page before being overwritten with the black-out notice. This will get attention.

The black-out information page

http://en.wikipedia.org/wiki/Wikipedia:SOPA_initiative/Learn...

says "The Wikipedia community has blacked out the English version of Wikipedia for 24 hours on January 18th to raise awareness about legislation being proposed by the U.S. Congress," but I see it also includes advice for residents of other countries about what to do about the legislation.

The information page even includes a response to the question "In carrying out this protest, is Wikipedia abandoning neutrality? Can I still trust Wikipedia?" The response is "We are staging this blackout because, although Wikipedia’s articles are neutral, its existence actually is not. Wikipedia depends on its existence for a free and open, uncensored Internet." This immediately suggests some other countries that it might be important to draw more attention to on Wikipedia. I wonder if that will happen. If it doesn't, I may indeed start doubting the neutrality of Wikipedia even more than I already do.

Mobile devices are exempted from the black-out, according to the information page, and anyone can turn off the black-out by disabling JavaScript. (I enable JavaScript on Wikipedia to take advantage of various Wikipedia editing tools.) I'll have to experiment with viewing the site some more, and I'll be curious to see what the worldwide reaction is. Again, I wonder what users will suggest what other countries to protest about with regard to Internet censorship.

AFTER EDIT: In another experiment, I posted a Wikipedia link to Facebook to tell friends about the background to my new favorite pop song. The link

http://en.wikipedia.org/wiki/Why_This_Kolaveri_Di

still shows correct summary text when embedded in a Facebook comment. That the links are still pasteable and still have usability when submitted to discussion forums is an especially nice aspect of how Wikipedia implemented its blackout. (P.S. The direct link to the official video for the new song, which is rapidly going viral around the world, is
