I agree with Jason that most people avoid networkign for the sake of networking... but there will always be that segment that believes any connection is a good connection.

I see your most active market being salespeople, recruiters, job seekers, and entrepreneurs.

The only thing with video calls is that they do take time to prepare for off camera, no matter how short the actual screen-time is, especially if they want to make a professional first impression.

I don't know if I'd be interested, but I do think people in the markets I mentioned would love it.
