Securing your name online can be as important as finding a physical location for a business, luckily TweExchange is aiming to help you out.

While there have been services out there for ages now that will help you with locating an unclaimed domain name, and there have also been a few to check for unusued Twitter names, no one has merged the two into one service before.  TweExchange is a new direction for a site that used to auction off desirable Twitter usernames (much to Twitter’s chagrin), but now they are all about helping you choose your online identity while you are still in the brainstorming phase.

The site is amazingly handy when you’re trying to decide on a name for your new online site.  Where you only used to have to worry about the domain name, now you also want a name that you can secure on the social networking site Twitter.  The site starts working almost immediately as you type each letter, showing you possible variations for both domains and Twitter names as you go.  Once you find one you like, you can register the domain via the built in link to the GoDaddy domain name service, and you can also click the link to go to Twitter and register the user name.  (click the image below for a larger view of what the results look like)

The site is simple, straight forward and a breeze to use.  If you want to start fresh with another search, just make sure to click the “Clear results” link below the “Search” button or else you get a jumbling of your previous search results along with the new ones.  As someone who dreams up a lot of sites, but doesn’t always get around to launching them, this site is going to be extremely useful to me.  If you want to launch a totally new online presence, this site should be invaluable to you, so make sure to bookmark it.
