What's obvious to one person is seldom obvious to everybody else.

You're preaching to the choir here. But when Warrigal announces some grand new idea, but just shrugs of even the importance of spelling out its implications, that's well beyond "not noticing something that's obvious to others" and into the territory of "not giving a s---, but expecting people to do your work for you."

As for being degrading, I was attempting, via irony, to help you to understand the impact of a particular style of comment.

Right. I "got" that the first time around (even before PS), thanks. That wasn't what I was referring to as "degrading"; it was actually pretty clever. Good work!

The degrading bit was where you do the internet equivalent of calling someone out in public, and then going through your accumulated list of their flaws, so anyone else who doesn't like the resident "bad guy" (guy who actually says what everyone else isn't willing to take the karma hit for) can join the pile-on.

In this case, it honestly didn't occur to me to send a private message.

Sure, because what you were trying to accomplish (self-promotion, "us vs. them")wouldn't have been satisfied by a private message, so of course it's not going to occur to you.

Other people seem to manage to PM me when I'm out of line (won't name names here). But that's generally because they're actually interested in improving my posting, not in grandstanding.
