As predicted by William Spaetzel (see the comments), Talkshoe has launched a new Facebook application (you will need a free Facebook ID to view this page).
According to Greg Schwartz who hosts my favourite show on Talkshoe, Uncontrolled Vocabulary, "this will allow you to listen live to Uncontrolled Vocabulary and participate in the chat room during the live call without ever leaving Facebook."
Want to try it out? Uncontrolled Vocabulary #33 is live tonight 10 to 11 pm Eastern.
More details about the Talkshoe changes in the Press Release.
