RSS, has no vowels, no information, and looks like an alphabet term you might see at the doctor’s office or in an HR onboarding form at a corpo.
Apparently is is called web feed, although I never have heard this until I searched off the back of your comment[0].
Apparently, web feed also encompasses Atom and JSON feed as well as RSS, which is probably more in the spirit of how people actually say "RSS".
1. How do you subscribe? 2. How do you post your own? 3. Do I need a browser to read feeds? 4. Can I view my feed from any device?
The current status quo for web feeds is very unfriendly to new users. If you click on an rss icon or an rss feed link, it takes you to a white page with a bunch of text that you don't understand. It just makes you think you're not supposed to be here, so you close the tab and leave.
Many feed readers are old and look dated. The UI can often be confused for an email client. And many of these readers don't support synchronizing feeds with different devices.
Here's the thing, one should not need to explain it no mire. Devices or applications accessing content with an RSS option should present it to the end user through a convenient interface.
Looking how podcasts advertise themselves, those who do use RSS advertise "Apple Podcasts or in your favorite podcast app" here.
You also have people producing "podcasts" that only exist on youtube.
