I like the way these guys think – let’s take audio conferencing and make it more visual. It seems to make a lot of sense. A simple to use interface that let’s you see who you are listening to, allows you to mute, exclude (via headphone icons) certain people at certain times, and link to extra information (social media etc) about the participants. The person speaking is highlighted. I am testing it with clients at the moment and it does exactly what it says on the site. And you can use it for free – find out more here (invite your friends and you unlock more features).
