I was introduced to Niki Scevak's blog, Bronte Media, by Dave and Andy here at Judy's Book a while ago, and I have had it bookmarked ever since.
I am always trolling the web looking for useful benchmarking-type numbers, which like anything especially useful, are hard to find. Niki posted some good numbers on Friday that shed some light on direct nav. economics, here, in his post about Sendori.
So here's a plug - more people should check in with Bronte Media from time to time.
