Heh

This is apparently a source of irritation among the younger crowd. Which is fine, since "text-ese" is a source of irritation for me.

Language is not a static thing; it changes and evolves. The Oxford comma (item, thing, and stuff -- it's the second comma) was once a hard-and-fast rule but is now considered optional. I've no problem with one or two spaces at the end of sentences, and either is acceptable in modern business communications. I use two spaces because it's hardwired into my brain after thirty years of touch typing. I average 90 WPM and type every day. After doing it for that long, I could no more stop double-spacing at the end of sentences than I could stop blinking.
