Started w/Yahoo! Mail long before gmail existed. Stuck with it due to incumbency, and a vague feeling [call me paranoid] that since I already use Google for so many other things, if they could also data-mine my email, they'd know almost everything about me. I don't [knowingly] use Yahoo for anything except email.
