I will suggest filtering, by term and by source URL. I think it would help customize individual feeds, making it easier and perhaps more comfortable navigating the news.
Example A: term filtering: This should be fairly obvious. Say I'm a Linux user who could care less about KDE. But people keep gushing over it in the Linux subs I subscribe to, and the damn developers keep pushing new releases that also get posted. Argh! Filter out posts (maybe even comments) that mention KDE, Bob's your uncle. And I can still enjoy all those delicious GNOME posts. Definitely not a real world inspired scenario.
Example B: URL filtering: Simply(!) filtering out link posts by source URL. Not a fan of Fox News and/or WaPo? Filter out one site or the other by root URL, like *.foxnews.com
or *.washingtonpost.com
.
Me, I'd gladly filter out all and any YouTube links unseen by default. That's a constant noise generator I could genuinely live without. But I digress.
I hope the examples illustrate my point because I could clearly never explain a feature request succinctly nor to the point.
