TypoTrawler scans eBay looking for misspellings. Savvy eBay shoppers know that misspelled listings result in fewer bidders, because they’re harder to find, so they offer the opportunity for getting a lower final auction price and/or making the item easier to win. You can select which categories you want to view and you can vote on which items are really misspelled or not, as well as click through to the eBay page.
They really need some kind of search function to make the service really useful but TypoTrawler, currently in Beta, looks like a cool site to keep an eye on for future developments. [TypoTrawler via Mighty Bargain Hunter]
