Tabber.org - A Virtual Address Book

Tabber is an online address book; import your contacts from a range of sources (Outlook, Digg, MySpace, MSN, etc.), or add them manually; once you´ve got all your contacts, use Tabber as you would any address book. Update birthday info, mailing addresses, get Google map directions, and find out what your friends are doing. Tabber lets you know when your friends make changes to their info, on Tabber or on their blog or MySpace page (you"ll receive an instant alert). You can also merge contact info if one of your friends has several profiles with different social networks, Tabber is completely free; registration is required.

“Tabber is meant to be used as an online address book, so if you ever need a friend"s address, phone number, need to remember their birthday, etc, you can go on Tabber and look it up. Tabber offers many more features than this though, allowing you to quickly get Google map directions to your friends" houses, organize them through the use of tags, keep up to date on what your friends are doing online, and be alerted of any changes your friends make to their personal data provided they are members of Tabber.”

Tabber provides an easy way to manage your contacts which means you can throw out your paper address book. It´s also got some nice extra´s such as the directional help, and the ability to keep up with what your friends are up to.

How will Tabber build a solid community of users? Other sites do the same and more. Will users find the features flexible enough for their needs?
