Funny how German podcasters pretty much unanimously decided not to do ads or sponsoring while american podcasts are often littered with ads to the point where it gets unbearable.

Compare and contrast the TWiT network or 5by5 with Tim Pritlove or BitsUndSo

Isn't the TWiT network a bit of a special case with Leo Laporte trying to monetize and self produce the same niche of programming he was doing with the Screen Savers back on ZDTV? There isn't much of a choice when the point of the screen casts are that they should be your job. Also it helps that we're conditioned to see adverts everywhere.

There was a time when TWiT was funded exclusively by donations, making a point of not taking ads in order to stay independent. At some point I guess the temptation become too big.

Another german one is Working Draft. Mostly front-end development http://workingdraft.de.
