I’ve long known that exclamation marks are frowned upon by writing gurus. As F. Scott Fitzgerald said:
“Cut out all these exclamation points. An exclamation point is like laughing at your own joke.”

I admit that I commonly use exclamation marks in emails to friends, which are more colloquially phrased…
Do you overindulge in exclamation marks?
