That is very interesting. I tried to make the pie chart appear here, but it didn't work.

Manybooks.net provides a running compilation of downloads-by-format, and their results are rather different. Let's see if I can make the current snapshot readable here:

I don't even know what Fictionbook format means. And note that they break mobipocket into three different groups.

My own rankings, which I posted earlier, are different from either of these. And Steve reports that his, for paid rather than free, downloads are different still (at least regarding PDF).

Looks like one conclusion is that it's different for every site. Possibly because the demographic types drawn to that particular site are different from those who go to other sites.
