My main takeaway on this is that if you build something that is naturally viral, chalk it up in the pluses column for that idea. Having an idea that is inherently viral is awfully nice, especially if you're a guerilla underdog. However, bolting on "viral" features isn't going to make your site really viral. That doesn't mean your site is a bad idea, just that you need to find different ways to get the word about your site out to your target users/customers. I think the point is that you shouldn't delude yourself, not that the only way to succeed is to build a naturally viral site.
