We used to add privacy to all of our domain registrations but once the new 2257 regs came out, it wasnt really worth doing as our address needed to be public anyway.

Thankfully because of how Florida law works we have a PO box as our official business address so its not to much concern to us.

Of course the other way of looking at it is....

Every time you make a domain private, that is money you could have used to purchase another domain name.
