Email newsletters are the new zines

I think the comparison with zines is interesting, but a newsletter on the best podcasts, or featuring a 'random medieval image' is not the heir to Sniffin' Glue. Anti-Establishment, the punk ethos, youth culture, that meant something. (Back when I were a lad, pass my slippers).
The nearest I've found is Tumblr, to be honest. The porny, angry, angsty, badly written, rapid fire, wonderfulness of that pile of zines on the record store counter.
Having said all that, I also find newsletters interesting. But as it stands at the moment they have a discovery problem (podcasts suffered the same way at the start). It might be gonzo to publish without an audience, because, hell-yeah, and stuff, but I don't see how anything but self delusion could make you think that means you're reaching more people who are 'genuinely interested'.
I'd love to read more newsletters, but those I've been recommended are mostly the same journalistic onanism or smug punditry. I've not found any distinct voice that isn't amply available across the internet.
NTK used to be good. It's never coming back, but I wish something was like it.
Perhaps newsletters need a digital library as well?
