When I search Google for "free" for example,
free - Google Search
the top site is thefreesite.com which has several other URLs listed under it and a "more results from the thefreesite.com" link. I've seen this for some other sites as well. Why are these sites listed differently and how???

They've only just introduced that fairly recently. Not really sure what the deal is with it, though.
