Do you mean that in google + i should participate in communities post add them and see if they add me ?
Gs use of G+ and other similar facilities is exploding in their face right now
Last week YouTube mandated users sign up for Google+, its social network, before commenting on a video, which links a YouTube account to an actual identity. The move touched off an outpouring of criticism, prompting a Change.org petition thatís collected more than 100,000 signatures in less than a week and a host of Reddit users to spam the Google products forum with more than 430,000 complaints. Even YouTube co-founder Jawed Karim questioned the policy on his page in the only other post visible besides his first video upload in 2005.
I'd say the preceding is pretty much a "facial explosion" wrt G+ being required for YouTube commenting.
Well if they want to protest, the most effective ways to do it would be stop using Google search and stop clicking on Google ads.
