What makes a good podcast?

Here are the ideas we came up during our discussion on what makes a good podcast.

• Music - for branding, to add interest, and to add production value
• Short intro (too long and we get bored)
• Relevance to listener so they know whether it's worth their while to listen
  
• Add interactivity
• Clear focus at the beginning
• Clear explanations
• Benefits for listening
• Use "show notes" with images
• Include the length of the episode in show notes
• Length 1 - 10 minutes
• Use an "outro" (wrap-up or ending)
• Make sure your personality comes through
• Make an emotional connection

I noticed that these ideas were similar to the ones listed in both the evaluation guides I distributed. If you want your own electronic copy, I've linked them below:
