Backup of David's Google+ Posts

I've claimed my custom URL for Google+. I'm at https://plus.google.com/+davidblume.  I wonder how much longer their old Profiles URLs will work. Mine was http://google.com/profiles/david.blume.  

But you know what's the most awesome Google+ URL of all?  I scored my username as the whole URL! I'm http://davi.dblu.me/+
