I found a new Twitter service this week called Tweexchange and found it very useful when setting up new Twitter accounts. The site allows user to determine whether a specific username is available on Twitter. If the name you want is already taken, it will suggest other names. It also provides a for-pay service to notify you if a name is on “pending removal” and becomes available to you. I didn’t know this service exists, so I found the article interesting and informative. Tweetexchange also includes a mention of a “GoDaddy” partnership which shows which domain names similar to your search are available.
