Thus creating a user-name that is also concise is of value. It can be easier for people to remember. It takes up less space when people are ‘retweeting’ things that you have said. It takes up less characters when someone is going to send you a message.

If only there was a way to see what small Twitter names were still available. Enter Little-Twit.

Little-Twit.com keeps a list of all the available one, two, three and four letter user-names. All of the one letter names are gone and most of the 2 letter names are gone as well, just 21 left. Plenty of three and four letter ones left though!

Give a check before they are all gone.
