Read It? Watched It? Swap It

Read It? Watched It? Swap It - New York Times: "Zunafish (www.zunafish.com), a new Web site that matches people with discs and tapes to trade — and video games and paperback books, too.

The site, which looks remarkably similar to a prototype Mr. Bloom sketched on notebook paper four years ago with Mr. Elias, trades only one-for-one items within the same category — CD's, DVD's, VHS tapes, video games, audio books or paperback books. No item (for example, a seven-disc DVD set of the first season of the television series "24") is worth more than any another (say, a DVD of Peter Jackson's "King Kong").

Traders using the site determine the relative value of an item by choosing to swap or not. No one is ever forced to make a trade. Like buyers and sellers on eBay, the traders on Zunafish rate each other, providing a confidence index for future transactions.

There are other online trading sites, including Peerflix and BarterBee, which started last summer, that offer trading in similar categories. But other sites tend to offer a more limited range of items, or they use more complicated systems, requiring points and memberships to execute trades."
