Get the RSS feeds you want.
(For YouTube, go to the channel page, right click, View Page Source, Find 'rss', copy that link.)
Paste it in Atomstr.
Add these to a List on eg Nostrudel, you can then have RSS lists show up in your feed, or see the List on Amethyst home. :)
*The last step is optional, you can just follow the account it creates.

That's all I know. I'm sure there's a better way of doing this lolol #asknostr
I would really like to see a proper #RSS reader, or RSS options integrated into a client. That would be amazing.
#Nostrudel might be the client crazy enough to do this lol @hzrd149
