Production values..
I like your podcasts, find 'em interesting and all that.
However, you can scrap the headset boom mike. I really don't want to listen to mouth noises. Makes the option of downloading the high-quality version moot - listening to mouth noises at a higher sample rate and higher quality is not what most people want.
Plese use real microphones with pop screens. Keep your nose away from the mike. Let me concentrate on the ideas rather than the spurious oral emanations.
'Kay? Thanks.
