Gosh, there is a lot of depth to language. I like lisper's note because there are a lot of people whose first language is not English and may not know the difference; I like your rejoinder that it was sarcasm against another audience, but was ironic humor to Google. (We can write to multiple audiences at once, no?)
And now here's a font complete enough that perhaps I can find the right glyph to punctuate the idea. We need something with a bit more nuance than the interrobang, I think.
