Still having a blast adding people into circles
? Well hold on tight, because Mountain View just introduced some worthy upgrades to its social network
. First up is a new feature dubbed "What's Hot" which, much like trending topics on Twitter, highlights popular content being shared on the social network. Photography aficionados in the audience can gussy up snaps with more photo editing features dubbed "Creative Kit", including a multitude of filters -- some of which (for a limited time) pertain to Halloween. And finally, those of you who use Google Apps within an organization can now partake in all the Google+ fun -- provided your IT admin isn't a social networking-hating luddite. Links explaining all that and more await you below, but before you go, why not hop past the break for some vampiric renditions of Larry and Sergey, and a few other celebs.
