most of us node runners would probably just us our getalby addresses because were already running AlbyHub and BTCpay server or LNBits is a pain in the ass to run because Start9 is behind TOR. Plus we like Alby :)
Changing the feeds is up to each podcaster to decide but for me if the other PC 2.0 devs cant easily add lnaddress support I'll never be onboard. These devs have been here the whole time and most do this for fun on the side and it they get left behind I'm out.
We chose keysend years ago because you can just sent payments to it and the server load is less.
PodcastGuru is working on it and I've seen demos of Castamatic so i guess were getting there but they are still using AlbyHub wallets that most listeners and podcasters say is too hard to set up.
We really need a wallet thats as easy for devs to use as the old Alby. Without the apps this all falls apart
