I have recently become disenchanted with the exclamation mark. I'm not sure where this feeling has come from, but every time I use one I feel a little bit cheap.
I came across a quote from F. Scott Fitzgerald recently that perhaps sums up my feelings: "An exclamation point is like laughing at your own joke."
I think it has to do with my minimalist self - always paring down to the essentials.
That said, if you are one of my favourite people who happens to use a great number of exclamation marks (of which there are a few), I find them charming when used by you. I mean it.
Punctuation marks I do like: ; & ?
