I know they're merely amateurs (although PBS seems to be open to a bigger gig ), however a few points of advice before I take an ice-pick to my eardrums for the next podcast:
1.) Dynamo_Hum needs to quit with the pause and sigh routine before any emotional or dramatic comment. This major annoyance is right on par or above anything Heater Wad does.
2.) PBS, don't ever believe (no matter what anyone else here tells you) that you are either a writer or broadcaster with any talent above amateur. As long as you know your place then everything is fine.
3.) The many Yeahs have to go as well. See #1 above. Yeah?....yeah..yeah..yeah/yeah/yeah...yeah!
Merely amateurs? As in they don't get paid for it? I can reel off several paid broadcasters both on radio and online who really shouldn't be classed as professional.
Presentation is subjective... Heard of the Beatles? McCartney and Lennon were told they'd never make it in music. I wonder what happened to them?
Incidentally, what are your esteemed credentials? Roughly.
