Remember Airtime, the Facebook-integrated video calling / media sharing service with a Chatroulette flavor? Well if not, we don't blame you -- usage stats suggest it hasn't quite taken off, but maybe the new features it's testing will secure a few more fans. No longer is the service restricted to the here and now, as the major change is all about video posts. Use Airtime to record a message and you can post it to Facebook, Twitter, YouTube or via a traditional email to get the conversation started. Friends can then reply to your message through Airtime with a video post of their own, and so on. Its buddy list has also been given a little love, so now it shows friends as online, idle or offline, and details your interaction timeline. Whether the features are enough to inspire wider uptake is questionable, but for the few that actively use Airtime, the updates are out in the wild now on a "limited public release."
