Google recently started making it so you have to register a Google Plus profile if you want to use any of their other services. They’ve also started pushing Google Plus shared items to the top of search results which forces the hand of anyone involved in search marketing to have a large circle of Plus followers.
From one point of view it can be seen as leveraging your assets. Others may see it as making a desperate push for a site nobody gives a rip about.
What do you think? Will it work?
Are you going to circle me on Google Plus?
