Well, you can't expect that, but what I am saying is that it is a blog, and I think a blog author should be free to write for his audience. Parent comment seems to say that you should write every blog post as if it is intended for the general public, which I disagree.
No, that's not even remotely close to what I said.
I'm saying it wouldn't hurt his case to write a small blurb about him being one of the designers of SML in the sidebar or to use language like "when we designed SML" or "the choices we took in SML," so it doesn't appear as if it's a wholly objective critique or even subject line.
