Indeed beauty without purpose is dead to Google's eyes.
Authority, or the appearance thereof seems to be the ultimate goal when dealing with SEO.
I believe many people get down and out on their luck and then watch too many get rich quick commercials on TV. So they put up a site and in 4 weeks time without activity they change their niche. They need cash NOW like the commercial said.
Unfortunately it is not often when a site will start making any profit in that amount of time. It can take years to achieve any real progress in a very large niche.
