It's not as trivial as you think. Research has shown that (aside from the "shouting" aspect, which I agree is trivial), on a more important note, that our comprehension of text based on all caps is very poor. So it may not be that people are offended... they are just naturally not getting full comprehension of the question.

This issue with comprehension may be more the reason why nobody is responding. Many just don't catch the impact or mission of the question.

I feel the majority of the posts regarding the All Caps issue were polite and well stated, but there is actually a more apppropriate issue. Same studies show that the two most comprehensible font are Times New Roman and Helvetica, so far as getting your message or question understood.

Now this may also seem trivial to you, but it's a big factor in communication and marketing. No fancy fonts and Upper/Lower case conventions, increase effective communication. That alone is significant in a world where we are not communicating face to face.

Now add proper spelling, short concise sentences, and many paragraph breaks and you have covered most of the offenses that detract from understanding communication on the internet.

I'm certainly not following my own advice all the time, but I try.
