[Steven Lake]

Since there's no "general ebook" section, I'll toss this question here and let the mods move it if they feel it needs to be. Anywho, here's my question.

I've been discussing the movement of all my books to ebook (yes, we're slow getting to it, but if you'd seen what our schedule has looked like the past 6 months, you'd understand why we're so slow. Heck, Destiny's Mission just got released recently some 3 months behind schedule!!) in the near future, still keeping the paperbacks for sale for those who prefer them that way, while appeasing all those who want to read them in the more modern format.

Anywho, one of the dilemmas that's come up is format. Being an open source advocate, I'm all for Epub, PDF and txt since they're all open formats, and possibly HTML, but I don't know of anyone who actually offers it in that format. That being said, I will also likely offer it in Kindle as well. I'd like to avoid that, since I hate proprietary formats, but since Amazon has everyone who posts stuff on their site by the hypothetical balls, I'm forced to offer it like that so that I can make my readers happy. (I wish they'd allow the offering of formats other than Kindle. Of course, if the courts have their way, they will)

But anyways, I digress, as I'm getting off topic here. The blunt of my question is this. Other than the 3 major common formats (Epub, pdf, txt), what other formats would you recommend that I offer my book in, or should I simply stick with those three formats, as it appears that almost everyone will soon be moving to supporting only those three?
