All WordPress.com blogs (possible also wordpress.org ones) have a feed: https://thanuir.wordpress.com/feed
All of them also have a comment feed: https://thanuir.wordpress.com/comments/feed
Just replace the url with whatever is relevant.
If blogger/blogspot or livejournal-hosted blogs have something similar, do share. I know how to access their normal feeds, no problem with that, but do they have comment feeds available?
