It always seems to be of curiosity to other authors where each of us is selling the most titles, and after seeing that question asked again this morning, I ran my numbers.
Here are my results.

It’s obvious that Amazon is my top distribution point. Smashwords has consistently been in second place, with B&N usually third.
It’s just as obvious that Diesel and Borders are, well… thus far, useless as distribution points.
Apparently, the larger portion of people who purchase my titles don’t consider Amazon an evil entity. 
Actually, I think Amazon does a better job of cross-promotion, so my titles are noticed and purchased more there than anywhere else.
I can do little more than mention I’ve released a new title, and sales start up on Amazon (sometimes before I even know the new release’s listing page has gone live, which I attribute to how well their onsite search works).
