And that PDF will screw up on an awful lot of readers, IME. If you're making PDF, and don't bother to make it properly, then it's going to put an awful lot more people off when the formatting goes badly wrong when their recently-updated reader shows one like per page, or whatever. (Let alone the devices, like my old, second-hand and now dead WinCE device which never handed non-Adobe PDF's well). I'll agree that this will lessen as a problem over time since PDF is now a fully open standard, but the effect remains for the moment since many devices and their readers were designed and produced before that.

And it says.. let's see, you're showing them as "PDF2". That's totally unclear, and you're relying on pop-up tags to explain what that actually means in the first place, given there is no "PDF2" format, and those pop-up tags won't display on many browsers (especially PDA ones!) in the first place. No wonder more people download the "untagged" one.

And your HTML is effectively unformatted... a common screwup, and I'm going to point at Baen doing the right thing here.
