Same experience. RSS is by far the most requested resource in the server logs. Sometimes up to 70% of the total traffic is coming from RSS. That said though, I wonder how much of that traffic is biological and how much is bots.

I also wonder how much is dead traffic. Dead as in people who add a ton of stuff in their RSS readers but don’t actually read.

RSS is a bit of a black box when it comes to this but maybe that's a good thing.
