Wetoku is a side-by-side video interface for interviewing people over 2 webcams. When I first saw it, it was amazingly clear & audible the same on both sides. You know how you watch an interview (or webinar) and some of the cast are super loud and some are so quiet? That’s very annoying. Well, this is just great to video tape two equally. If you are an early adopter, you’ll like this blog tool.
