> I hear people have some success with Patronite these daysMoreover, direct donations [1] are working quite well, at least for the popular podcasts. (But then, only the very popular podcasts make a fortune anyway.)
Here in Germany, SEPA standing orders are quite popular for fans to support their favourites.
Also, buying stuff and sending that to the Podcasters is quite popular for some formats (either specialized stuff like high-quality chocolate from people working in that business, or just buying random stuff from a podcaster's Amazon wishlist.)
[1] Well, legally this is still plain income rather than donations, so you still have to pay taxes. Unless, of course, that income is very small and/or you create a non-profit organization around your podcast.
