You know, I was about to defend myself, but you may be right. My tone of outrage at the slurgfest being wrong was itself rather wrong. If he didn't see the long term incremental improvements this tool offers, that's nothing to be outraged over. People make mistakes.

That said, I think it's a stretch to call this mistake of mine an ad hominem attack. It doesn't fit my normal understanding of such an attack - there was no name calling, etc. And certainly I didn't accuse him of an ad hominem.

Thanks for pointing that out. I made slurgfest's comment a proxy for slurgfest when I interpreted your comment, and that is indeed a stretch. I agree that neither of you were all that harsh.
