As promised... From Kevin Drum's blog on Mother Jones, in a post about how end-of-sentence periods are rarely used in text messaging and can actually come across as offensive:
"Luckily for me, I almost never text or IM, so I haven't been inadvertently offending people. Normally I do that by writing snarky blog posts that turn out to sound a little more hostile than I intended. But for the rest of you, start dropping those periods unless you want to come across as an imperious martinet. You. Have. Been. Warned." http://www.motherjones.com/kevin-drum/2013/12/rise-and-fall-lowly-period http://www.motherjones.com/kevin-drum/2013/12/rise-and-fall-lowly-period (Somehow I don't think any of the scoffers who accused me of lying about the periods-between-words convention are going to apologize... You'll actually have to read the post to see how clever Kevin's use of it is in that context.)
