While I'm not sure why Lerma thinks Kiptronic is a podcast network, he mentions some very good points about how he sourced potential podcasts for his client:
Check out iTunes top podcasts in the category of interest
Listen to the shows to ensure there is some level of quality
Check out the show's site to see how it will impact the brand
Point #3 is important. We podcasters like to think that the show is the whole thing, but it's not. Our show blogs have an impact and it can be a good one or a bad one. Lerma brings up a very good point that potential advertisers are probably reluctant to deal with "one of" podcasters which can go maverick on them and damange the brand.
There are essentially two types of podcasters. Those of us who don't care if we ever make a cent from our shows, and the other kind. If you're looking at being a pro podcaster, then you'll have to brush up your image to attract the likes of Travelocity.
