It makes me go crazy to have 'successful' people have a junior-high grasp on English. Think through your contractions. You're in consulting and marketing, to many extents, so how do you think it looks to write (mildly) poorly and unprofessionaly?

Just keep an eye on your yours, you'res, itss, and it'ss!

Good post, though, I hope it enables mucho discussion.

And this is not meant to be demeaning, but I bet we can both agree that the presentation of the package is just as important as the content.
