that most people find all caps difficult to read, and also it gets interpreted as shouting, so by using all caps, you might lose both the impact and the subtlety of what you're trying to get across. It is of course your choice.
It's easy to misinterpret posts and emails, even with emoticons, and what was meant to be a suggestion may come across as a demand. I think we're all a little better off if we're willing to give people the benefit of the doubt when it comes to the perceived attitude of the post. For example, "kiss my ass" would generally be easily interpreted as intentionally rude. But unless you tell me otherwise, I'm going to assume that you were being ironic rather than angry, and I'm hoping that others will as well. Fair enough?
Peace.
