Let's be clear: Anyone who has a domain name like weblogs.com to sell, even with zero content, is going to make quite a bit of money. They are scarce commodities, and that has nothing to do with blogging. I hardly see how it's fair to include that in the total. If I registered movies.com years ago, and had a blog about movies today, it would be a bit silly to attribute the millions I would get from selling movies.com to my blog.
