A very good idea. I, for one, will be happy to Patre-nize your Podcast because you work very hard at doing it and you give all of us wonderful esoteric news of the oddities (and additives) in the World of Food. WOF in my book.
Even if one can give a few pennies, it is a gesture toward all of the energy you put into your Pod. James Beard may still be in your future.
