Pretty well required reading at the moment if you’re interested in the consequences of Google integrating their own social products into their search results. I’d really recommend reading the whole thing but, if not, at least take a glance at Danny Sullivan’s takeaway:
It’s not Google’s job to be sticking it to anyone with its search results. Those results are supposed to be showing what are the most relevant things for searchers out there. That’s how Google wins. That’s how Google sticks it to competitors, by not trying to play favorites in those results, nor by trying to punish people through them.
The Google+ suggestions are indeed search results, to me. Right now, they’re search results on who to follow on Google+. I think they could be better search results if they were who to follow on any social network, anywhere.
