G+ is very good for SEO. It is also a niche market that someone needs to tackle. I have yet to dedicate much time to it because I do not feel it has the general consumer has adapted to it. Facebook and twitter have a much better general acceptance at this point...not to rule out G+, Path, or dare I say it...the new MySpace. TWiT has a great weekly posdcast, The Social Hour http://twit.tv/tsh that anyone interested in social should watch and learn from. They mention that you should pick the one or two spaces that you are good at--Twitter, FB, Path, FourSquare, G+, instagram, etc---Pizza Hut said it the best. Figure out what you are good at and stick with it. The most important thing is that we as Agents & Brokers are adaptable. That is what is going to make or break us all in the future.Got the offer code from TWiT.tv's The Social Hour podcast. Great podcast on everything social media.
