how do they make money online?

I currently work within the automotive industry in Guelph Ontario . My job pays fairly well but I have been reading on how people are making money while they sleep online. This sounds like a much better job then mine. I also read about a guy that made a million pixel website and sold each pixel for one doller. Who whould have thought of that ? So anyways I have been researching a lot and I put a page together with the money making ideas that I have been  trying so far. http://cashcow.co.cc/

Ive never blogged a day in my life and I thought that it  would be worth a try!. I know generating traffic through any site is probably one of the best ways to make money. such as http://cashcow.co.cc/ .

Domain name flipping seems to be a profitable business but you need to invest and it's really hard to find lucrative names. It's crazy how much these names can go for if you get the right one. I almost feel off my chair when i read this list for most expensive domain name sales.

1. Insure.com, sold to QuinStreet for $16 million in 2009.

2. Sex.com, sold for $12-$14 million in 2006.

3. Fund.com, sold for $9.99 million in 2008.

4. Porn.com, sold for $9.5 million in 2007.

5. Business.com, sold for $7.5 million in 1999.
