Sell it. Quickest way to profit at the least expense. Otherwise you have to build a product/service, build the business, and then build the brand.
The best "brandables" are niche collections
example:
wikiCars
wikiTrucks
wikiAutoParts
wikiVans
wikiMotorcycles
wikiRentals
etc... it looks more interesting to higher priced domain prospectors if you are providing "the space", but it ups the initial investment.
