After browsing for a few minutes I found that it really needs to have some kind of filter mechanism.
For example, on old.reddit.com each post has its individual feed, while on blogspot you have both RSS and Atom feed.
What's funny is that desktop versions of websites in a lot of cases are responsive, and work fine on small screen. BUT at the same time the mobile version is crappy and lacks some features (or just shows "download our app").
Recently I've set up Firefox on Android so that it always run in desktop mode. I needed to also change screen width in about:config, because otherwise everything is too small. But after this websites seem to work better.
