I have never been able to sigh into Flickr with anything other than by Facebook ID. All attempts by me/Yahoo to create an Yahoo ID that wasn't locked in some self defeating loop failed.

I've never been a fan of Yahoo or for that matter Hotmail; they force an ID on you which is then hijacked by their email servers to spam all your contacts...again...and again.

Why can't Yahoo just die gracefully ? Why do they have to inflict their death throes on Flickr Users ?
