And, putting on my evil marketer hat, the goal here isn't to spread a message; it's to grow the size of the list. To use the network effect built into these social sites to its maximum potential. If this time if you have 400K or so participants, your leverage those in the right fashion? Next time you should easily be in the millions. The mailing list potential alone could be incredible. You could just harvest email addresses and network connections, then wait six months and send out a mailer that kind of starts off like "Joe Smith referred us to you because he knows you're concerned about X....." And then, if you were really evil, you'd pick up interests from all the friend links and incorporate that info as well. I want to be clear. I'm not saying these guys are doing any of that. I'm saying that once you agree to be a zombie like this, the effects can be very far-reaching indeed.
