When travelling by air it's nice to have a bunch of feeds to read.
I have found significant issues with this. Many websites don't offer the full article on their RSS feed.
For example Ars Technica. I use miniflux, and it only shows me the first paragraph. Using the Download button in miniflux to download the whole article does nothing.
lire ios app can offline sync and can pull the original article instead of the rss stub. i use it with a local freshrss instance that i have accessible via tailscale
