No RSS logo is visible for me on the blog pages, but inspecting the source reveals the 404 link below; deducting from that I got 200 results:

What doesn't work for RSS (CC +Marco Cantù) as you get 404 or no result:
- events
- individual questions
- individual blog posts
Failure examples:
- no RSS: https://community.embarcadero.com/all-events?format=feed&type=rss
- 404: https://community.embarcadero.com/answers/problem-with-form-height-in-ide?format=feed&type=rss
