I mean if browsers hadn't gone out of their way to remove RSS discovery, it wouldn't be necessary. I don't remember if I mentioned this in my above post and I don't want to re-read every word I wrote, but I've got the NetNewsWire Safari extension which finds feeds for me. Pretty sure I also have some extension in my current Firefox install, but I haven't opened that in a while. Sometimes the feed really doesn't exist anymore, which is unfortunate.

I use a service to create feeds from pages if they really don't exist. It's a paid service, but worth it!
