Re: I'm not surprised.
I assume everything else that happened in "the JBOSS community", including apparently everyone else sitting back and letting Scott steal credit without comment (it's possible perhaps that third parties discreetly e-mailed Scott to say "Dude, no", but since that didn't work, a time comes for "public" criticism.
Even if "My First Guide to JBOSS" was a ragged bundle of ill-informed fallacies, rewriting ought to be undertaken with credit given and ideally with consent as well.
...Unless that "My Guide" itself was, or appeared to be, largely swiped from someone else's material. Including, and I might have gone about it this way, a work that's an anthology of everyone's forum posts. And if two people go about producing a document that way, they will present the same material, including the same errors.
But why am I not taking the story at face value? I have no reason to distrust. But there is often more than one side.
Incidentally: I just signed up to https://dba.stackexchange.com/ mainly to ask certain questions - one of which, I first searched for previous applicable posts, twice; found something that said "Read this 'white paper' document" - so I did - and then next one - and decided I now don't need to ask about that. Although it might have saved my time to do that - but used up other people's.
So, good documentation is good. (However, I sent a couple of document revisions to Microsoft... no, wait, I didn't, it wouldn't send it. I'll try later in a different web browser.)
