Thanks for shedding some light on AddEvent. To be honest, I prefer my Oz mysterious and behind the curtain; I don't want to know how big of a sham it is. You have a database storage engine shrouded in complexities. I grasp Kalen Delaney's explanations on the same level as quantum mechanics - sort of, kind of, but not really. Then you have parts like of the Report Server that feel like they were hacked together by college juniors cramming on a take-home final. Don't get me wrong - Reporting Services is pretty solid now. But thorough documentation would make me a lot more willing to make database calls under the cover.
