During this summer I posted a bit about Gmail.
I started with the assertion that Gmail wasn't going to kill Yahoo! mail or Hotmail. I think email addresses are pretty sticky for most people, like phone numbers are.
Well we've got some data, thanks to our portfolio company Return Path, and it looks like it confirms my instincts on this one.
Gmail is adding email users at about 1/20th the rate that Yahoo! and Hotmail add accounts and they are not taking that many accounts away from these two email giants.
Matt Blumberg, CEO of Reurn Path, blogged the details earlier this week.
