One part of the plan is a great idea regardless: building a mailing list. Even a once-weekly email can give you a once-weekly adsense boost. Nothing wrong with that. Put up 10 sites that are on the same niche, with a different focus for each. Make your email newsletter about a topic related to a different one of those sites and rotate through them. The list will grow from sign-ups on each of the 10 sites. Pick a general topic that you love to branch into the 10 sites. It won't happen fast, but over time (a year, say), you'll have a nice list that you can advertise to over and over. Make the focus good content (on the sites and in the email newsletter) and you won't have a big drop-out rate. People who appreciate your newsletter content will be more likely to visit your sites and click around. I think it's a good business model, if you have the time and the patience.
