Come to think of it, for as long as I can remember, nrss played second fiddle to canto. And that may be as the developer intended.
Either way, I don’t remember much about how nrss worked, and might not ever, since the version I built in Arch segfaulted at any keypress.
So beyond opening the initial screen and watching it auto-refresh, nrss wouldn’t do much for me. Of course, if it’s prepackaged in your distro, you’ll probably have better luck.
A note on configuration: There’s a folder marked “feeds” inside
~/.nrss/ but nrss only worked if I put this line inside
add "http://feeds.bbci.co.uk/news/rss.xml" "BBC Top Stories"
It may be that there is a better way to configure nrss, but it might be late to figure it out.
Between the two, nrss or canto, you can decide which you prefer. I don’t use news readers much, and don’t really see a difference between them.
If you use them and need certain features, see if nrss has them.
