The writer of the blog Joy the Baker talks on the phone to the writer of the blog Shutterbean. A baker and a photographer. You'd think there would be some great insight into baking and photography...and there's some...but mostly random convos between two funny ladies.
Another podcast by Joy from Joy the Baker. This one has some more substance when it comes to the subject of baking. She interviews some big names in the baking/blogging world.
Both of those are sponsored by homefries.com and they have a few other podcasts that sound just as great: The Simple Mom, The Crush (wine), The Table Set and The Because Show. All centered around food and funniness.
A non-baking related suggestion is Dave Ramsey's new-ish podcast about his leadership program, Entre Leadership. They play a segment of Dave's philosophy on leadership, then interview someone who's a leader in the business world. Some great interviews are Chick-fil-a's Dan Cathy, Zappos' Tony Hsieh and NFL coach Tony Dungy.
Watermark Community Church also has some great material up for grabs. You can search through tons of categories and listen to messages, workshops, Bible studies, etc. on various topics.
So that's my 2 cents on podcasts in case you're sick of the Christmas station on Pandora at work. I've been there.
