I still remember being blown away when I switched. I'd given up on SPAM. My wife still uses Yahoo and sometimes I'll go into her email to help with something and be shocked by how much she gets. Spam control is also the reason my two daughters have Gmail accounts so Google is capturing the next generation. (On a random side note my kids were actually disappointed when Buzz went away. They were all using it as their first SN experience as they were too young to be allowed access to anything else)
