- be web based
- be cross platform (so I can use it on phone and desktop)
- be light on network and fast to load
- have simple design
- should have folders
- sort by oldest
- mark all as read (in the folder)
- be optimized for text, not pictures
and that's pretty much all.
What it shouldn't have is: - fancy design
- too much pictures
- ads
- unused empty space
- feed discovery and any "social" features
Of course, it should also be free.In the end, I might just as well backup my feed list for the reference, but try to live without RSS reader for a month or two, just to check do I really want to switch to another one.
In the end, I might even consider some lightweight self hosted variant.
EDIT: Thanks for the suggestions.
