I just paid $10 to own a link from a word in The Big Word Project dictionary page.
The idea is that as a viral concept you buy a word for $1 per letter and link that word to the site of your choice.
You could of course link to a blank domain and then resell the domain if it became a valuable property.

Strange concept but overnight my word generated 20 or so hits.
(Hint : my word is something that relates to my profession.)
