since when...

Since when did it become cool to stop using correct punctuation and/or capitalization? For example, most "cool" people use lowercase i instead of uppercase I. Or they forget to capitalize the beginning of a sentence. Or don't capitalize their titles. Yes, I have, at times (such as in this post), done the same thing, but I think it's time things changed around here.

From this day forward, I will strive to use correct punctuation, spelling and capitalization. This is my solemn promise.
