"Exclamation points are good, exclamation points are impressive, but it is the words that do the work." --Ryan Healy
I noticed during the last two promotions that when I used lots of exclamation points, readers wrote to tell me the copy sounded "hypey." But when I omitted all the exclamation points, I received no such comments.
Kind of interesting, don't you think?
By the way, I swiped Albert Einstein for the above quote. The original says, "Thunder is good, thunder is impressive, but it is the lightning that does the work."
