I was checking one of my websites - Neolimit.info(PL) and I’ve noticed something strange.
There’s a leaderboard between menu and content, but this time it had something more then just few titles+descriptions.

Just look:

There are few links in the left-bottom of the AD Unit.
When I’ve put cursor over one of the links, I saw JavaScript function call.
I don’t know if it works just like a normal text link - I didn’t click it - but I guess it is, because the links are much more revealant than normal Content Ads(like Text Links unit).
I think that it’s a very good idea, I hope that Google will use this format in future.
