I dont know what sort of site you run and whether you consider it to be a business.
To my mind, any business should at least have a name and a postal address visible somewhere. I put this at the bottom of my privicy policy if not on the contact page.
I'm not talking Google+ here but I believe you must lose some credibility if you are anonymous.
