Yahoo has other security issues too.
When LOGGED OUT of Yahoo! the little icons in the corner still tell me how many emails I have. The site is identifying me regardless which, in turn, provides an avenue to gather information without being logged in. Anyone spoofing my IP and/or retrieving my Yahoo cookies can see how many emails I have waiting, as well as my log in name.
