Yeah. For me it started out as a combination of experiment and laziness. once the OGL stuff broke I figured I might as well keep going that way. if I go the distance and end up wanting to do something with it, there should one game or another released under ORC by then.Systemless seems like the way to go, to me, especially if you have even a vague intention of sharing it with the public in any fashion.
If nothing else, I hope the last few days has made more people realize how easy it actually is to use systemless books. If it says "gnoll" in the adventure, just grab your relevant monster book and use that gnoll. The stats in the book are nice, but they've never been mandatory.
