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

I just checked and I found a few working RSS feeds :
https://community.embarcadero.com/index.php?option=com_easyblog&view=latest&format=feed&type=rss
https://community.embarcadero.com/article?format=feed&type=rss
https://community.embarcadero.com/article?format=feed&type=atom
I used the BriskBard web browser to get those links but I’m sure other browsers have some kind of extensions to detect the RSS feeds.

Thanks; seems they fixed a few things since I scheduled the post back in 2017: https://gist.github.com/jpluimers/4903ac79b0cba02393dcd64f9d194637/revisions
Note https://community.embarcadero.com/blogs/entry/cpp-japan?format=feed&type=rss still is a 404, despite https://community.embarcadero.com/blogs/entry/cpp-japan working fine.

A funny coincidence, this summer I thought I finally need to start on that RSS-reader of my own. It’s here: https://github.com/stijnsanders/feeder
