Right now Google Plus is the latest buzz online. New services, addons and plugins regarding Google Plus are getting launched everyday. Just few minutes ago I found a new service related to Google+ called MyPlus.name that allowed a person to get a customized URL with a username of his choice.
This service is free and you are not required to signup for it. All you need to do is to copy and paste your Google Plus profile ID and enter your the username of your choice and straight away you will get a URL that will be redirected to your Google Plus profile.
For Example purpose you can checkout my own customized URL: http://www.myplus.name/jb
