There are a few distinct use cases for RSS readers with very different requirements for automatic filtering.
I use RSS readers to keep up with infrequently-updated fiction and webcomics. In this use case, "suggestions" are worse than useless - if I miss a daily or weekly strip or, worse yet, a chapter being posted, that can cripple my enjoyment of the story. I check my RSS feeds once ever two or three days and read exactly every single post in them, all twenty or forty of them.
There are other people (myself about six years ago, for example) that use their RSS reader as a news firehose. They get a hundred posts an hour and even checking their titles manually would be difficult. In this case suggestions are not just a good idea but actually required.
Personally, I'd like an RSS reader that has a per-feed toggle for automatic filtering. I so far haven't seen that.
And even both at the same time. I have a set of comics and low-frequency posting blogs that I want to always read every post, in order, and defer them if I didn't want to read it right now. And then a firehose of other articles that I may or may not be interested in reading and can skim it to see if I want to read it, and then open it in a new tab and continue.
I feel like it's challenging to get both of these use cases in the same app. I could do it in google reader by having categories, but when it closed I switched to Inoreader and it does the "helpful" thing of only showing the last 30 days if you want to read it in chronological order, and used up my mental energy switching and basically just gave up RSS after that and haven't read them in a long time.
I'm in a similar situation regarding use case - some busy news feeds, where I'll just scan the titles and read a few articles of interest, and plenty of comics that aren't updated daily, and thus can't slot conveniently into an OmniWeb workspace.
