"That’s not marketing, it’s an annoying hobby." - epic line.
So why aren't more businesses jumping over to Google+? My guess is that it is a combination of three things at least:1. Clinging to the hope that huge numbers on FB will somehow make up for its weaknesses.2. Believing the G+ is a ghost town stories (or actually experiencing that your customers aren't active here).3. Lack of understanding of SEO, the importance of search in the buying funnel, and how strongly Google+ plays into those.
Excellent points Mark, let's break this down. With your first point (This is such a great point) we're coming across a derivative of the sunk cost fallacy where companies will throw up their arms and memos and say "Hey! We just spent all this time and money on Facebook, why would we waste our time with a brand new social network?" Fair question, right? Instead of huffing and puffing a shrugging we need to take the next step and truly sell them on it. Never easy but if you focus on the impact of such a move you should be effective. Keep in mind, we have to sell them on the benefits, the cost, and the return. Without any one of the three we're just pitching "good content." This is a great post from Wil Reynolds that covers some great, related points: http://bit.ly/ND2jjg
I think Google+ is still a "techie" community. EVERYONE is on Facebook, and it doesn't seem like that's going to change until they piss off the core audience that posts pictures and such. They weren't built by businesses, they started with college kids and became a business. So Google+ is still B2B as opposed to business to consumer. Just my $0.02.
