I consider Jason a friend (http://blog.stackoverflow.com/2009/06/podcast-56/), a very smart guy, and a great entrepreneur, although I have a different philosophy than he does on how to build a Q&A site.
I do the best I can not to comment on competitors, although I can't always live up to my ideal.
There are a lot of companies built on the business model of making low-cost, low-quality pages for long-tail Google search results, either algorithmically or with low-paid humans. There's clearly an arbitrage opportunity there, providing some kind of semi-crappy web page on a topic so narrow that there isn't anything on the web yet, but low quality content doesn't interest me at all.
