Namechk is a new service launching on Wednesday that helps you find open usernames at 84 different Web sites. Like UsernameCheck, a service we covered last year that has since shut down, it takes only a few seconds to come up with the results and provides a link to the page for each user at the sites where it's taken.
What's really impressive about this service is the speed. In a few sample searches, it averaged about 8 seconds from start to finish. And you don't even have to wait to see all the results because they stream in as it does its business.
