Google+ creates long numeric user ID’s and has – at least at present – no way to select your own vanity URL (like your name or nick).
That opens up for services like gplus.to which offers you to create a nick or vanity URL for your Google+ account.
If you have a domain of your own and can modify your htaccess-file then it’s easy to create your own personal vanity URL’s. You simply add code like this:
Redirect 301 /me/gplus https://plus.google.com/google+idhere Redirect 301 /me/facebook http://www.facebook.com/bengt.wendel Redirect 301 /me/twitter http://twitter.com/BengtWendel
