What do you think about time outs for children?

We have had many discussions about spanking on fluther. This one is about the pros and cons of time outs, being sent to a corner, a naughty chair, or something similar. Do you use them with your children? Did you have time outs given to you as a child?

If you had time out as a child what do you think about them in retrospect?

I didn’t have time outs. I think they became popular when I was already much older. I had never even heard of it until my 20’s I think. But, maybe it was being utilized as a discipline tool and I was just unaware.
