I came here from Feedly.
> Ask HN: Is RSS dying? Or coming back?
Feedly has about 30mn of downtime now and then; I'd say once a year. /s
It's not dying, thus it doesn't have to come back.
> Is RSS still actively developed as a protocol?
I don't think it does, and I like it.
> If not, why not?
Why should it? Don't break something that works.
> Are there any viable alternatives on the horizon?
RSS is viable to me. I understand that some may want to add tracking and paid suscriptions; but that's not a bug, that's a feature. I don't want some content pushers to constantly try to ram something down my throat -wasting my precious time- just so that they can make a few cents off my back annually.

Here's my advice: take the habit of actually seeking information. You saw a thread on Facebook about Photogrammetry? Then research how it is done. When you stumble on a source that is useful to you, try to identify if new content may be produced; and try to find an RSS feed. Boom, you're now subscribed to a Palaeontologist's articles about macro-Photogrammetry, how he captures details in fossils:

It's called curating information for your own needs; come back in a few years to thank me. By then you'll have gone a few rabbit-holes of technical specialization, and have an information pipeline way better than the 3-seconds-attention-optimized Facebook's feed.
