In episode 145 of Semantic Mastery's weekly Hump Day Hangouts, one participant asked if it's okay to flood posts in Google Plus.
The exact question was:
Hey guys, I just got done with the Rankfeedr webinar on Maps SEO, and I'm about to start on the Twitter to G+ applet mentioned in the July SAV2 update webinar. Both involve making a lot of posts on the G+ page. Is this all okay? I know from a user perspective, it doesn't matter since no one uses G+, but does Google see anything fishy?
