I don't really mind the email interface that much, my main issue is that most RSS clients have it exclusively, without any second level of automatic filtering/sorting/triage. For many feeds that I subscribe, I'm only interested in portions of it, or I would want to filter out some topics, etc. So I have to manually go through heaps of stuff that only mildly interest me or often not at all, to find the few things I wanted when I originally encountered the blog.
