Do you assume someone is stupid / of questionable intelligence if they write an email without:
Capitalization
Salutation
Proper / any punctuation
I run the other way when someone sends me an email like this:
Yoshi: Hello, my name is Yoshi ButterCookie and I am curious about your purple widgets. We initially discussed that they would be available on or before the 15th of June, 2010 (today.) I have not yet received notification from your company that the widgets Boss ordered are ready. Please let me know.
Response
purple widgets not ready.
[big huge signature here]
Yoshi: Mr. Assface, as of today, June 16, 2010 the purple widgets are late. As you can imagine time is of the essence and I need a timeline as to when I can expect them.
Thanks,
Response: purple widgets wont be ready. find other purple widgets.
