The internet is the perfect medium for matching supply with demand. You can find your next freelance job or, as Craigslist has been singled out for, find just about anything else (if you know the right euphemisms). Now, with Data Marketplace, you can also easily request or provide datasets covering anything you can think of:
Data Marketplace makes it easy for people to find, buy and sell data online.
People request data that they need. Providers upload data to Data Marketplace, provide descriptive metadata, and set a price. Stored metadata is used to help consumers find relevant data through traditional search engines and when browsing the marketplace.
At the moment there are not a lot of datasets available, and those that are available cover fairly standard topics like ZIP codes, stock prices and life expectancy. Far more interesting are the requests, like data on permits for pizza restaurants, email addresses of hedge fund managers and stats on people trafficking.
It will be interesting to see if Data Marketplace can complete with the freely available data being pushed out by governments around the world (like the UK and US), and services ranging from Wolfram Alpha to Infochimps.
But with the obscure nature of some of the requests, Data Marketplace is sure to find a niche.
