Google Blogoscoped reports that, Google is now showing other sub-domains among the sitelinks. Now, sitelinks are the navigational links displayed below a main result. Google displays them automatically for certain websites or queries.

For example (from the image above), if you key in 'ask' as your search query in Google, then Google also shows othe sub-domains such as 'uk.ask.com' below 'www.ask.com'. This is something new and people are waiting to hear an explanation about this from Google. Whether it is just a test, or Google is actually going to implement this feature for other websites as well?
