@wolfadeus - do you mean you haven't noticed TA and YELP occupying multiple organic slots over the last year or so? This is what i mean by the artificial boost. Why specifically raise those multiple positions, when Google won't likely hold them down the track. They are also not usually good for users in multiple quantities. Why?
There seems to be a business strategy associated with it in my view.
Get folks used to content that it will replace with it's own assets maybe. Y/N?
