I want to start earning some good money online, just like everyone. Before I start creating websites I want to know which is the better alternative and which one will bring me more money in the long run. I can create 15 to 20 wordpress micro niche sites each with 10 articles from RSS, paid, hand made, etc. Or I can create a 1 custom web 2.0 authority website in rails targeted to a specific niche. For example a social bookmarking site for sunglasses. I will spend 1 week on this. Which one of these two option do you think will bring me more money?
