I haven't noticed it for some while now, but it seams you can still crack one domain -only – subdomain listings taking over the SERPs.

For example keyword: "representatief werk" (dutch for "representative work") shows only 1 domain in the top 10.

http://www.google.nl/search?q=representatief+werk

Interesting because it's a common word, and the top 10 listing have variable in the urls (offset!) thus shouldn't rank well.
