I dunno, Hugene...looking at the email addresses in my larger db, they beat out google and yahoo.
I've had a hotmail account for over 10 years. I used it when I didn't want to give out my "real" email. Slowly, it has become a useful secondary account for me, mostly for e-commerce.
The spam filtering used to be awful, but in the last 12 months it has gotten better.
