Yahoo! is starting to get aggressive about asking for my mobile phone number and I absolutely refuse to give it to them. It's already required for new accounts, and now they're trying to get old accounts updated. While they may be asking nicely now, it's only a matter of time before they require me to provide my mobile phone number just to log in. I want to be prepared for that, so being able to export both contacts and my emails would be a great way to get the jump on them.
