What is your opinion of exclamation marks?
Elmore Leonard said that "Keep your exclamation points under control. You are allowed no more than two or three per 100,000 words of prose. If you have a knack of playing with exclaimers the way Tom Wolfe does, you can throw them in by the handful."
It is amazing to me that I can make significant judgements about a person who seems to have such an extreme view.
I often read also that in the business world, the usage of exclamation marks is decidedly unprofessional, something which I don't particularly agree with but I suppose you generally have to live with the system.
