Do you really expect a service as integral to the Internet as Google to shutdown entirely? Would they want to give people an excuse to try Bing or another search engine? What about their shareholders?

Their shareholders will have much more to worry about if SOPA passes. Plus, Google being completely down in protest for a day would be a huge PR win; it would make those that stayed up and running look ridiculous. Wikipedia's approach is the strongest and most likely to actually sway people into action while Google's will be largely ignored by the public.

That is seriously weak. The phones would be ringing off the hook if Google stopped service instead for 24 hours. As it is, everyone will simply think it's another cute Google doodle.

A dot after the tld

That's actually how it's supposed to be done:

http://www.dns-sd.org/TrailingDotsInDomainNames.html

"It's a little-known fact, but fully-qualified (unambiguous) DNS domain names have a dot at the end. People running DNS servers usually know this (if you miss the trailing dots out, your DNS configuration is unlikely to work) but the general public usually doesn't. A domain name that doesn't have a dot at the end is not fully-qualified and is potentially ambiguous. This was documented in the DNS specification, RFC 1034, way back in 1987 ..."

but the site works just fine without the trailing dot as well.
