> Gmail does not, inherently, have any network effects (unlike FB, messengers, any other comms tool of Gmail's scale) That's not true at all. I've noticed when sending from Gmail to Gmail it always gets delivered and quickly. I've noticed with other email service people, even ones using big providers like Yahoo, it's really hit or miss if they can receive from me, send to me, and it takes a long time to show up in my email. So there's a really strong network effect to use Gmail because Gmail doesn't work well outside Gmail. So much so that I keep a bunch of address (personal/Gmail, work, school, my personal web site and email server) and try to pick the one that works best based on who I'm sending to.
