Listees,

Thanks for the many comments.

As I warned, the results are preliminary. One prominent seller
pointed out important omissions in my data (items sold via "Buy
It Now" in particular). I'm debugging and rerunning.

Since there is sufficient interest and since the reports are not
small, I'll set up a little Web page for future results. Stay
tuned for a pointer.

It'll be fun to look at data over time.
