If you were to submit a paper to a conference or a journal and they asked you to provide an abstract -- would you be offended? Why not? When you read ACM or IEEE journals, do you see the abstracts as "dumbing down to TV-style sound bytes"?
Let's put it this way: if you can't figure it out from the title of the article, it's just not for you.
The article was not meant for people with a casual interest in the subject, but those who wanted to know about the details.
If that's not you, so be it. I would note, however, that at this point you've surely spent more time complaining here than it would have taken you to read the entire article.
He is not writing for the ACMA or the IEEE. He is writing a blog. There is no need for an executive summary! His article is fine, it took me no longer than 3 minutes or so to read it. Great article!
I figured the title was enough to give away the general gist of the article: it's about a programming language and the problems it had. If that's a subject that interests you, perhaps the article is worth a read. I wrote the article to talk about a subject I know well, for people interested in that subject.
tl;dr: not everything can be dumbed down to TV-style sound bytes.
