This made me laugh, so I decided to share.
As a Yahoo! mail user for over 6 years (at least that's what the email told me, if I remember correctly I was 12 when I signed up and it was in July (I remember because I was at a friend's birthday party) so it's actually been 9 1/2 years) I have to say that I have never been disappointed by it in the least. Also, I have subscribed to each new beta version when it came out, so here I go to load my new Yahoo! Mail Beta.
Wow! Look at the confetti!
