Some kind of Chat is a great way to engage listeners. Particularly on a "Listen Live" screen.

I'm pencilled in to host a weekly, 2 hr internet radio show and will probably be using a single purpose Skype account for interacting with on line listeners.

I had considered Yugma but didn't want the distraction and added resposibility of monitoring a chat.

Here's the setup Towncrier uses when broadcasting & the host wishes to interact with the audience. http://www.towncrierbroadcasting.com/ChatRoom
