cardmagic / contacts to import email contacts (GMAIL,Y!, etc...)

Hello, I'm looking for a solution to allow users to import their
contact lists. The Contacts Gem seems to be the only solution out
there.

Is it correct that the contacts gem screen scrapes and doesn't use the
provider's APIs to import email addresses? If so, why? Why not use the
APIs?

I've heard of the Blackbook gem, but I don't know if it's still
maintained.

Why not check the source?

Best,
