TalkShoe Support Live

Should a Host be succinct or loquacious? Community Calls are afterall really about one, two or more people conversing on topics of mutual interest, either on a live show or via a pre-recorded chat uploaded for others to further enjoy. Is the host there to keep things focused and on topic? Or are they there to allow free flowing discussion, the expounding of ideas, the injecting of insightful observations and/or interesting or amusing asides?
