I have started using Google+ more this year and trying out the new communities section. If you have tried Google+ in the past and did not like it, or even if you have never tried it, I ask you to give it a shot. The system seems to have stabilized over the last several months and it is growing daily. Much less dramatic than Facebook, it has its own feel and attracts different people than other social sites.
If you do decide to try Google+ head over to: https://plus.google.com/u/0/communities/102384480548369345288
I have created an Osprey Publishing community where members can discuss history, military strategies, and the future of publishing.
I hope to see you over there.
