I just want to say,
right on! The referer field is being abused by just about every RSS aggregator. Instead of
Referer, they should be using the
User-Agent request-header field to identify themselves. My guess is that they also want to show up in referrer logs for marketing reasons...because they're more likely to be read by site authors. I block them specifically from my referrer reports because they're meaningless. (Has anyone compiled a comprehensive list?) But I shouldn't have to.
