Ok so today we officially STUMPED the Genius Bar at the Apple Store.....so any help that I could get on here would be AWESOME!

So here is the problem:

I manage about 2,500 of my contacts online at nimble.com. When I have them on nimble and try to export them to the Mac Mailer program it takes at least two steps to format them and make sure that they are in the format I need, and then get them into my address book.

Do any of you know an online solution that can manage contacts, as well as have these features:

- Be able to group/tag certain contacts together
- The ability for the online contact management system to update contacts as their linkedin profile changes
- Sync with Mac Address Book

Anyone know of such system?! Help!
