When looking at a question, for at least the past few months I've noticed an inconsistency in what displays in the righthand sidebar. What I expect to see is a list of "related questions" -- first the ones linked from the question I have open, followed by others that the software thinks are relevant. I can't get an example to screenshot right now, but this functionality has been around as long as I can remember and I hope folks know what I'm talking about. One potentially relevant fact is that on many Stack Exchange sites, there are ads here or links to questions on yet other Stack Exchange sites, but I believe MO has been fairly unique in always having just links to other questions on MO here.
But sometimes (and maybe with increasing frequency?) this list of questions fails to show up, and instead I just get the text "Question feed" with the little RSS icon next to it. (EDIT It looks like "Linked Questions" are showing up for me, but not "Related Questions".) Here's a screenshot:
(See what I mean on the lower righthand side?)
When I click on it, it says something about setting up an RSS feed:
I suppose I'm some kind of Neanderthal, but I've never felt the need to set up an RSS feed, I don't know how they work, and I don't understand why I should need to just to see the related questions for a question I'll probably look at once and never come back to. Neither refreshing nor turning off my adblocker seem to make a difference. I use Chrome on Windows 10.
Does this happen to others? Is it a feature or a bug? Is there something I can do to fix it?
I did find a meta question listing RSS feeds related to Stack Exchange but as far as I can tell none of them seem to be related to this.
