Google just announced that GMail is now open to all - no more of that "invitation" nonsense. What's interesting, though, is this AP article reporting Google's intention to add a paid to service to GMail (thanks, Avinash):
"Now that Google has more computing muscle, Brin said the company will start selling additional storage capacity to e-mail users with extraordinary needs. Google still hasn't figured out the specifics, but Brin indicated the e-mail storage and fees to be introduced later this year would be similar to Google's photo-hosting service that charges $25 annually for 6.25 gigabytes and $500 annually for 250 gigabytes.
'We can't afford to give away everything for free,' Brin said."
All I can say is: affiliate program, please- thanks!
