You can get a cool shortened Google+ profile url address at http://gplus.to/. For example, mine is http://gplus.to/larryferlazzo. It’s pretty easy to use but, if you need a simple tutorial, you can get it here. You only insert a portion of the long address to get it shortened.
I’m adding it to The Best Resources For Learning What Google+ Is All About.
I found another website where you can create a short url for Google plus, http://glpl.us Check it out!
