I would rather see people use all lowercase letters - a la e.e. cummings, than all caps. It's just hard to read. And don't even get me started on people who write without using commas, periods or paragraphs. We all learned how to write properly in elementary school.
Every once in awhile, I press my caps lock key by mistake. However, it's pretty obvious when that happens so I delete the letters and start again using proper capitalization.
This morning, I was reading the comments on one of my favorite blogs. Someone wrote a comment in all caps - and then apologized for it. If you don't want to write in all caps, then don't! It's not like they make keyboards that only write in capital letters. Grr!
I realize I sound like a giant cow. However, I write for a living, so things like this bug me. I'm sure supermodels are offended by people who eat too many cheeseburgers, accountants are bothered by people who can't do math and fashion designers are offended by people who wear crocs.
Plus, this is my blog so I can be a giant cow if I want to be.
