What makes you shudder? And what are your commitments?

I belong to a LinkedIn group called Grammar Geeks, where one of the most popular discussions right now, with 269 comments, is “What Makes You Shudder?” Each of these 269 entries contains someone’s comment (or more often complaint) about a grammar gaffe.

At first I was interested in some of the conversations… but quickly, the conversation itself was the thing making me shudder. In fact, I began to shudder each time another member of the group posted a complaint. Even the word “shudder” began to make me shudder!
