Website UsernameCheck is your one-stop shop to check the availability of your preferred user names on various websites – Flickr, Del.icio.us, Blogger, FriendFeed, YouTube, Stumble Upon etc.
Enter your username, click check and sit back as the site checks for the availability of the username and displays results. The websites checked seems to be updated too, as even Tipd, a financial social website launched recently, has found its place on UsernameCheck.
For example, I found that the username Obama is still available on some popular websites like FriendFeed, LinkedIn, Mixx and Yahoo. You’d wonder why nobody has (yet) taken them.ADVERTISEMENT
