question: why gmail? or, to be more precise: why are so many people salivating over it? check craigslist, ebay, or any number of barter/trade sites, and the amount of traffic in gmail invites is kind of staggering, with demand far outstripping supply. so... why? do that many people really need 1GB of email storage? or is it because google has such a "feel-good" corporate image that everyone wants in? or is the invite-only beta just a brilliant freaking piece of marketing? please explain... i'm just a cave-man. i don't understand your modern viral marketing concepts.
