Viral Marketing - Another Set of New Clothes for the Emperor?

fingal asks: "I've recently started working for a company who has decided that viral marketing is The Way Forwards. I've got mixed feelings about this. As the sysadmin who has to deal with the aftermath of hosting our own stuff and dealing with the inevitable congestion associated with the (rapidly increasing) size of attachments that are routinely moved about, it just winds me up. On the other hand - I very much enjoy checking out what people are up to (except when they email it to me and I'm on a dial-up...), but I don't think that I've ever actually bought anything as a result. What does everyone think about about this (either from the viewpoint of a consumer, provider or infrastructure engineer)?" Here is a better definition of the term "viral marketing". What are your thoughts on this subject?
