The comments feed looks great. (I use Feedly on iOS.)
Let me know if you spot any issues.
Looks fine using QuiteRSS, too. ( https://quiterss.org/ )
Though browsers don't use that stuff anymore, but it can't hurt to add something like his to the front page HTML, right?
<link rel="alternate" type="application/rss+xml" title="RSS" href="rss">
https://www.laarc.io/newcomments and https://www.laarc.io/ now works with QuiteRSS.
It'd be easy to add feeds for each tag, too. Something like /l/music.rss
