Well, but you have an user experience =) So, do you find it too clumsy if there are two feeds - one for content, another for comments. Or is it too much trouble having to subscribe to two separate feeds?

This site runs on Drupal, and it seems to store comments differently than normal content. The way it is built, there doesn't seem to be an out-of-the-box way to build a list of both content and comments sorted by time. To figure this out, I'd need to dig deeper into the inner workings of the framework, either finding an easy way to combine two feeds into one, or then just writing my own code for it (in which case I'd also need to study a bit more of RSS, if I'm going to write a piece of code generating a feed.) At the moment all of this might take more time than I feel like investing into it. So if it is not too much trouble for users, then I'll go forward with separate feeds, and improve the system later on.
