I went digging into my gmail account and realized that I got my original "welcome to gmail" email on May 18th 2004. It has been 4+ years and it went by FAST!! The only other email program I recall giving me as much joy for such an extended length of time was pine. That was when i went from never having an email account to my first encounter with the wonders of email. All the other programs I have encountered in-between and since including Notes, Outlook, Yahoo, Hotmail, Zimbra, Mail(mac)have not been memorable. Wonder why?
Here is to the next decade of gmail innovations! :)
