On top of SlashDot, I found an entry which talks about Viral Marketing. The link is at http://www.washingtonpost.com/wp-dyn/content/article/2006/12/11/AR2006121101389.html?nav=rss_technology. When I first heard about that, about more than a year ago, it seemed like the new way of doing advertisement, as it was bypassing all existing spam policies in place. But, then again, there is always abuse in all kinds of things. Could it be that this will not last very long?
