Yes, and it works, nobody outside SL can see nothing that i marked as "Second Life", but they can see that i'm on Second Life, cause google found me. As an example, Facebook lets you choose if you want to be found on google or not. Obviously, if you point your web browser to http://www.facebook.com/tualet.rivera as if you point it to http://my.secondlife.com/tualet.rivera, you can see my FB/SL profile.
