I don't use them, but it's a hereditary thing.
When my sister was a baby, and I was ten, my mom refused to use pacifiers. She called them something like "bozo-nose clown suckers" because she thought they looked so stupid. I don't think it had anything to do with breastfeeding.
I originally didn't like them because I grew up hearing how stupid they were, but when I learned more about breastfeeding and the problem of nipple confusion, I decided against them. I didn't want to introduce an artificial nipple to the baby and make it harder for him or her to breastfeed. If you do it after the first 6 weeks or so (I think?) nipple confusion isn't as much as a problem.
My other issue with them is that I don't want another thing to keep track of. Whenever we're at church and there are kids around with pacifiers, the parents are always bending over to pick them up off the floor. I don't want to have to worry about losing them, getting them dirty, forgetting them at home, etc.
