It's a known fact that sex sells. In fact, if you want to sell something, promote something, or get people to look at something, you need a sultry women with come hither eyes starting at you. Men don't care what she is selling, they will stop and look, and become convinced that they need it.
Women on the other hand get sold on sparkly things, and shoes, and the word SALE. Have a commercial with a women in cute shoes, she will be all over it. Same with having sparkly stuff. Women eat that up.
Even in this enlightened age, its still the same. Look at any commercial, you see scantily clad women prancing around selling something or the other. Sometimes there is a scantily clad guy at the beach doing the same thing.
Its the same with online photo albums. I use a hosting service called pbase, and take great pictures. There is also several other's that take the same type of pictures I do( nature and wildlife). On average we receive less hits then those with the nude shots, or women pics.
The ultimate election campaign involves a well built muscular man, and a hot female VP. The female attracts the male and female votes by wearing next to nothing, but cute shoes and glittery eye liner. The man stays out of the picture and only gives interviews at sporting events, wearing rhinestone shirts, and positions himself in front of any sign that says sale.
American people are so easy to manipulate.
