One example Website is:
Badger Badger Badger.com! The Original Dancing Badgers!
That website has been going since 2002. Adsense have not removed their ads so it must be acceptable. The owner must be making money.
Others too such as:
RainyMood.com: Rain makes everything better.
I was thinking of finding something similar, and creating a Website just like that, then getting the website to go viral using Social Networking Websites.
What are your opinions on this?
