I know a guy that used to make sites like this. The gibberish you see is scraped from somewhere and its purpose on the site is to give Google bot something to see and rank the site for search terms related to the content. There's a PHP script running behind the scenes and when users from a certain geographic location or meeting some other criteria happen on the site by clicking on it from an organic link in Google search, the content is switched out for a page full of affiliate ads linking to eBay, Amazon, or whomever.
The "thin" sites with this stuff are generated by a script and the spammer will create thousands of them on cheap hosting. The economics work since it usually takes Google a few months to boot the sites from organic search but by then the affiliate money has been made that more than covers the cost. And the whole time Google is pulling the sites off their search page, more sites are steadily being generated.
