Well, it's not insider information. Matt Cutts mentioned it on his blog. It's organic ranking help of some kind, although Matt wouldn't go into detail about it.
I've noticed this mom and pop boost several times with friends when I helped them put their one-man show on the web. Even their TBPR was soon higher than their few backlinks would seem to justify. I've also posted about it over past years, too.
It's not enough of a boost to knock the big guys out on a big trophy keyword - but it is enough to get some impressions and traffic into a small new site.
