Oh, I can understand... In spite of my criminal and unthinking overuse of ellipses, commas, hyphens, slashes, and parenthesis, I am similarly obsessive about certain aspects of (poor) grammar.
I am no good at typing... I am always somehow misspelling words like "remember" and "definitely" in a flurry of keystrokes, and unwittingly typing the wrong "they're/there/their", two things (obvious poor spelling and lacking a grasp on the most basic elements of grammar) that I cannot tolerate in professional/real-life situations.
I can understand it better online though. I am essentially brain-dead and operating on auto-pilot 90% of my time spent in front of a keyboard (which is incidentally 90% of my day)... So I make embarrassing/stupid typos I'd never make "IRL" without noticing them until three hours after making a post. I figure a lot of folks must be the same way.
PS: Great blog...
