US$1 a letter - TheBigWordProject.com

With more than 4500 words "bought" - the creators of The Big Word Project, Paddy Donnelly and Lee Munroe, want to revamp the way we define words. The Big Word Project lists over two thousand different words (the list is continuously growing) and for the price of one dollar you can associate that specific word with your website or blog.
The two creators were interested in different interpretations of words by different individuals, and so the website was created in part to explore and play with the definitions of words. For example, Jorbb has bought some words related to Jorbb.com.
With nearly all 291,500 Oxford English Dictionary entries in inventory — plus verb forms, plural nouns, comparatives, superlatives, and American spellings — Donnelly and Munroe could be millionaires very soon.
