I suppose it's just a pet peeve of mine. It's an effort to read some post in which the writer doesn't bother to punctuate- not because they can't but because they figure they will just let someone else work to figure it out. I certainly wouldn't know a past participle if my wife served me one for dinner. However, I think we do the young a disservice when we say the only thing that matters is getting your point across. Like it or not, we live in a world in which people draw conclusions about us based on the language we use, and how we wield it. It might not matter when your talking about wiper motors, but when applying for a job, competing for a promotion, or vying for a contract, you can bet it does. In the business/corporate world where many of our kids will find their niche, good writing and speaking skills will seperate the haves from the have nots.
I remember many years ago soliciting bids for a computer system for a private school.
One of the emails I received was so poorly worded that I showed it to my children and posed this question; What is your opinion of this person's command of the subject matter? They conclude, perhaps incorrectly, perhaps not, that the person wasn't very smart.
