Spam will find a way
As a blogspot blogger, I received an invitation to join the beta test for Google's G-mail service. I haven't been using it yet, having decided to hold out for hotmail's reaction, and have only logged in twice. I've not sent a single email, let a single person know about the address or even posted the email address, but, sure enough, spam has found a way.
In logging in this morning, I was greeted by something about 'Best of the best' which came through as source html and someone angling for a Gmail invitation from my new best friend Herb Green (who's clearly been smoking some).
For all the hype of the new product launch, you just can't escape good old spam.
