Lots of bizarre logic here:

> Not only is it not a large portion of your keystrokes, but the space bar has your two strongest digits dedicated solely to it!

double-tapping a key is harder to execute than other key pairings.

> Well that’s not right! Vim can’t easily tell the difference between the period after “Mr” and the end of a sentence. > Two-spacing provides more semantic information,

If this is your concern, it's far more appropriate to use a different symbol/glyph for non-breaking dots.

> So the next time you see that arrogant Slate article, feel free to be arrogant right back.

True. That Slate author's writings are unjustifiably smug.
