I've been working for Google, giving out Gmail invites for a couple of weeks. Well, they don't call it working, they call it “Invite a Friend” but really, I was working for them. Now, they're going to pay me back of course - I fully intend to use as much of the 1G of space that they have given me and I will never, ever, click on an advertisement link.
So I figure that I've signed them up around 30 people, and if those thirty people sign up 6 people each and so forth, you can quickly account for every human on the planet having a gmail account. I did my part helping them, but I do feel a bit duped by the whole private invite thing. People were selling invites! Come on!
Anyhow, the product is good so I don't mind having vouched for them, and hopefully I'm leaving them on good terms.
