Facebook video chat is limited to one-on-one calls, unlike Google+ Huddles which allow for group video chat, or even group simultaneous watching of YouTube videos. There are certainly some practical business applications for the group aspects of Google+. Hopefully, Facebook will continue to expand on the video chat concept and include a group video chat function at some point. What would really be cool is if Facebook, Google+, Skype, Apple FaceTime, and any other competing video chat platform could all get on the same page so they could all work together, but I won't hold my breath.
The initial implementation of Facebook video chat may be a little rough around the edges, but it is still good news, and it is a valuable tool that businesses can start taking advantage of immediately with the other 750 million Facebook users.
