I've given my share of boos, all in fun when giving a member their first boo (booginity)
Today, I was reviewing all posts I came to one and immediately reached for the thumbs down button. I hesitated. I reread the post, then hit the button. My first real boo given (that I can remember).
THEN, I noticed it was boo #2. So I wasn't the only one that didn't like the post.
