MonetizationMethods.com I like this domain and there are a ton of people who are looking for this kind of stuff so I'd say it would be a really useful website. There aren't too many quoted results in Google for the name (around 7k) but I think that you'll be able to fetch Mid XX in the resale market and possibly XXX to end users. TheWebMillionaire.com Undeveloped I don't think this has much value. It seems like an obvious name for an e-book so if you made a website and branded an original e-book with it the value would increase substantially.
I agree with the ebook thing. That was what came into my mind when I saw the domain. Maybe somebody will find that domain useful in the near future.
