But cool technology isn't nearly as cool as cool technology that's very popular.
Need an example of why?
http://www.gmailswap.com/ (if you need one, or have one to give away)
http://toolbar.google.com/gmail-helper/ (notifies you of new messages even when your logged out)
http://www.marklyon.org/gmail/ (upload your existing mail to your Gmail account)
http://jaybe.org/info.htm (POP3 for Gmail)
http://richard.jones.name/google-hacks/gmail-filesystem/gmail-filesystem.html (mount your 1gig of storage as a filesystem!)
Of course GMail isn't all sunshine and roses…
http://slashdot.org/article.pl?sid=04/08/28/1853234 (Gmail changes login protocol to block third-party notifiers)
http://gmail-is-too-creepy.com/ (for thoes who somehow got the impression the web is a secure place to transmit your private materials around, this should shatter that reality nicely. Of course this is MORE true of things like... oh, I don't know... your workplace? Your ISP? So don't pull a chicken little when you read this, ok?)
But if you ask me, it's the only way to do email.
