I am a little intruiged by Yahoo's whole system of bidding. They say that the minimum bid is .10, yet when I set any of my keywords to that level and hit the 'update' button, they stay at .11.

Even more strange is I have noticed that when there are multiple bids, there are plenty of people who are in there at .10. Whats going on here? Do they only bump you to .11 when you bid on a word which no one else is on?
