Why, welcome back. :)
I kinda like Google+ myself – for one, I like how it allows the use of bold and italic fonts in posts. I tend to use it for sharing more "serious" stuff, and leave the cat pics for Facebook.
By the way, is there any Google+ group about nuclear power you'd recommend joining? I find that I've got much more up-to-date with the robotics industry since joining the #Robotics
group, was wondering if there was some equivalently active group on the nuclear front.
