I'll grant you that your comments are, for all intents and purposes, readable.
I'll further grant you that missing commas and poor spelling is more annoying.
That said, a number of 1500+ posters have expressed their disdain over a lack of proper "netiquette" including a lack of capitals (I'd go back and point them out, but I'm not sure I want to waste the time, and you can do it yourself).
Last, and probably for the third or fourth time, why is so hard just to do it correctly by pressing the shift button? Not sure why you're having difficulty addressing that question.
