I've used it, and it worked well, but I don't really have a need for social video chat in my life that Google Hangouts doesn't already solve.<p>We use Hangouts for work meetings and such, and while I don't use it for much of anything else, I just didn't see that Airtime offered anything above and beyond, except Facebook integration.<p>That isn't to disparage Airtime, it's really quite slick, honestly, and looks like a good acquisition for FB if they're trying to get into video.
