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.Not sure on Wordpress, but I have heard great things on squarespace.com. Not sure about he MLS integration, but I know it does support a ton of third party app integration. If you use offer code socialhour5 to get a discount.
