I hate to be That Guy, but I found the massive overuse of exclamation points to be very distracting. I'm not quite at the level of those people who claim that using exclamation points is like laughing at your own jokes, but they should not be a default punctuation choice.

There are 62 exclamations and 54 periods (counted after removing the periods in code sections).
