Is It Useful To Send Social Signals To A PR Or Money Site?

 

In episode 211 of Semantic Mastery's weekly Hump Day Hangouts, one participant asked if sending social signals is useful for a PR or money site.

The exact question was:

Marketers Center also have a Social Shotgun service that sends social signals from FB, G+ Twitter +10 others. Would that be good to send to a PR or money site?

Thanks Happy Thanksgiving guys!
