The MillionDollarHomepage sold a million pixels at $1 per pixel but the Million Dollar Wiki plans to sell 10,000 pages at $100 per page.
Million Dollar Wiki is similar to Wikipedia; however, each page can only be edited by its owner at the cost of $100 per page. The “business” page for the Million Dollar Wiki has just sold for US $6,100 on Ebay.
Owners of pages are also encouraged to purchase pages for re-sale later; someone may be willing to pay several hundred, or even thousands, for a page that boasts a popular keyword such as Internet or Music. Link
