Today Google added My preferred sites to Google Experimental Search

http://www.google.com/experimental/index.html

Mmmm... no.
"The experiment you're trying to access is no longer available. Go to experiments overview"

Odd, I get the option to opt-in to this feature, but when I do it still doesn't show up on the preferences page they link to. Is this still being rolled out?

It doesn't show for me too. Perform a search on Google and you will get the same message I posted before.

Show's up for me correctly in the US.

Tom and Philipp
Same problem here

OK it works here, only if I add "&gl=us" in the URLs (SERPS & preferences pages)

anyway, I can't add sites. When I press the "add site" button, nothing happens, surely because the "gl=us" parameter isn't in the request.

I get the same thing Philipp mentioned..
Really odd.. :/

This should be the URL for using the preferred sites experiment:
http://www.google.com/search?q=google&esrch=ps

But there's a yellow bar that says:
" The experiment you're trying to access is no longer available. Go to experiments overview "

Colin, you get this yellow bar?

On the other hand:
http://www.google.com/search?q=google&esrch=blogoscoped

lol.. :/
