A simple tip for make a redirection in your domain to your google plus profile.
In the nginx conf file for your domain only needs to add this lines:
if ($request_uri ~ ^/\+$){
rewrite ^ http://profiles.google.com/yourprofileid permanent;
}
And now, you can share a new url http://yourdomain.com/+ for google+.
In my case http://agustinvinao.com.ar/+
[update] this sentence must go after the server directive:
server_name agustinvinao.com.ar www.agustinvinao.com.ar;
if ($request_uri ~ ^/\+$){
rewrite ^ http://profiles.google.com/agustinvinao permanent;
}
