What does Skydeck do?
Skydeck helps you to manage your cell phone, your cell phone bill, and the contacts you communicate with using your cell phone. For example, we enable you to see all of your call records in one place, link them to your contacts, tag and annotate them, and search your calls the way you search your email. Additionally, Skydeck will use the information in your cell phone bills to intelligently organize and rank your address book and allow you to network with others on the site.
Once Skydeck logged onto my cell carrier it downloaded my cell bills for analyzing. Then it asked me to import my contacts to cross reference. I used Gmail but they offer Outlook, Yahoo, Hotmail and Plaxo.
It will put the contacts in a rank. The rank is based on your call usage from the bill. It even gives a nice little 5 bar scale. You can add your own picture to each contact to make a little more visually appealing. You can ask your friends/contacts to join Skydeck so that you can link to them as a connection. This is the part I am not sure about yet. I will need to find someone willing to link to me to see what it's capabilities are.
