One of the most dreaded nightmare of any heavy web user is that the username he seeks is not available. I never had such a trouble because of my unique name but the random web users like Tom, Dick and Harry are not that lucky. The have to tweak in names by putting in zeros and hyphens which to me look ugly. Your username is your identity on web and as far as possible it’s wise to have one username. This helps in creating a brand and removes the confusion of remembering different usernames as well.

UserNameCheck can help you determining what username you should choose so that you can have the same username across all popular websites. This AJAX based web service allows you to check the availability of your desired username on 68 websites and the prominent among them being twitter, gmail, yahoo, WordPress and StumbleUpon etc.

I thought this might help.
