AddyMate - a smart address book with enhanced privacy controls

Hi all, I'd like to get the HN community's feedback on a web service I've built out of the Washington, D.C. area - www.addymate.com. You can use the code ADDYINVITE to signup & access the features. AddyMate is a FREE service that helps you easily lookup your contacts in one place by keeping them insync with your Google & Yahoo address books. It is also a place to safely share your contact info with others while controlling who all can see which details using AddyMate’s enhanced privacy settings. AddyMate supports the linking of your Facebook & LinkedIn accounts so that you can automatically connect with your social & professional connections on AddyMate when they sign up as well. It has all the functionalities you'd expect from a contact management service that's relevant in a socially connected world via a easy & intuitive user interface built to quickly get you in touch with your contacts: - Full 2-way contact sync with Google & Yahoo; - Sharing your contact details with your Facebook & LinkedIn connections; - Finding & merging duplicate contacts; - Address book import from Hotmail, Outlook & Windows Mail; - Access to your contacts from your phone. Looking forward to hearing from you. Thanks, Rajdeep
