This is one of the most important things in this discution, If you do not actually own a website then you basically have no say, Just because of the face that you dont have to deal with cost of running a site. Why constanly use money that you are making in real life to spend online if your not even getting a "kick back' i might aswell just throw money away everymonth. But in my situation im making enough money in ads to pay for everything online PLUS stuff in my real life. If you ever own a website you will understand how important ad revenue is. Ads are very benefical. Some site's do go way over board, But the owner knows that he can load up the site with ads and he knows that he still wont lose any traffic
