Don't believe everything people say because frankly it really depends on the market you are in. I have several different niche market sites and they all get different conversions. I have a site that has 4000 members and i get one out of 9 that pay. It's really niche though. It's not main stream. Now, for main stream then yeah, those numbers would be correct. If you have a main stream site then you need hundreds of thousands but who wants to start a main stream site right now anyway? The money is in niche markets.
