I stopped using Yahoo the first time I setup an account for a friend and they were already on Yahoo's spam email reseller list faster than I could disable the opt-out setting. There was spam waiting in the inbox on an email account less than 5 minutes old.

I appreciate some of what they've done for the larger community, but decisions like that which make users take such a distant backseat to the bottom line make me not want to be a yahoo user ever again.
