While this site is pretty cool to see where a site ranks and who linky-love's back to them, I don't think that it's cool that it shows the contact info for that site if the contact has registered with Amazon.
Yeah, I know it's an "amazon.com" company, but sheesh, even on their wishlists, it doesn't show the contacts address. Even though it looks like you can remove/update your contact info (which may take up to 6 weeks to update), it seems odd that the default would be to show the address in the first place.
Seriously, how many people know that that specific information is out there without their permission? I mean, do you think Matt would mind if I dropped over to his apartment, because I happened to find (or searched for) his site rankings and got his apartment number? Seems a bit of an invasion of privacy to me, and I think it should be addressed, so I emailed them at customerservice@alexa.com.
I wonder if they will reply. (And, yes, I know I am late to the party, but that bugs me even more that it was brought out a year and a half ago and it's still the default).
