I really dislike the buttons on the bottom of the posts on Ravelry and other forums. ESPECIALLY the "disagree" button, it's to vague and frequently misused. It seems that sometimes people use it just to be mean. I was much happier when I learned how to TURN IT OFF!
I agree that sheer numbers makes it easier for people to be cranky but it still takes me by surprise when someone posts something looking for support and they get torn to bits. It's like the only place some can flex their muscle is the internet!
GinnyG on Ravelry, I'd LOVE to be in your "friends"
