What kinds of podcasts and vodcasts are people creating?

One of the greatest challenges (for me, at least) in creating a new podcast or vodcast has nothing to do with technology--it's deciding on a topic. While the possiblities of what you can talk about are endless, here are a few examples I've found on what other people are talking about:

Current Events

You can hear top news, commentary, and reports on popular culture--sometimes all from the same source:

Rocketboom (Web site) (feed info)

or let the world know about current developments from within your own organization:

The University of Chicago: Research at Chicago (Web) (feed info)

Culture

Enjoy a slice of life through biographical sketches of an individual or subculture you maybe never considered before:

Fly With Me (Web site) (feed)

or focus on one of your personal interests:

Travel with Rick Steves (Web site) (feed)
Eat/Feed (Web site) (feed)

Professional development

Get career advice:

Management Tools (Web site) (feed)

or keep on top of developments in your field:

The New Jersey Legal Update Podcast (Web site) (feed)

Teaching and training

Others are syndicating recordings of traditional lectures:

Computer Science E-1: Understanding Computers and the Internet (Web site) (feed)
(NOTE! Please consider the FERPA guidelines before distributing recordings of course lectures)

and distributing supplemental educational materials:

English as a Second Language Podcast (Web site) (feed)
The Princeton Review's Vocab Minute Podcast (Web site) (feed)

as well as sharing tips and tricks for software applications:

Dr. Photoshop (Web site) (feed)

Because RSS enclosures allow you to distribute any type of file, you can distribute materials like PDF handouts and PowerPoint presentations along with your audio and movie files:

The FrenchPodClass (Web site) (feed)

Tell me more, tell me more
