For those of you looking for a shorter url for your google+ profile, you can use the
http://gplus.to, or, if you have your own domain where you can create an .htaccess rule to handle a redirect:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^g\+$
https://plus.google.com/123457890 [R=301,L]
</IfModule>
Replace the url in the rule with your profile url, upload the file as .htaccess or, add the lines to an existing .htaccess file.
Then, when you go to http://yoursite.com/g+ you'll be redirected to your google profile account. Now, you're in control of your own url and don't need to worry when gplus.to is slow or down. Nor do you need to worry about whether those services will eventually shut down for lack of revenue, or, start putting interstitial ads in.
You can also use any of the link shortener services to do the same.
