You've seen MOO cards, those adorable half-the-size of regular business cards that have a pretty image on one side and your info on the other. Today MOO.com announced a big step toward social business, integrating with Facebook to create real business cards that use images from your Facebook Timeline. The customizable cards are available now for purchase. MOO social business cards fit into the Timeline mission, which hardly differentiates between online and offline identity. With MOO business cards, Facebook wants you to move one step closer to imagining your identity on social media less as you and more as "you," also known as your very own personal brand of yourself.

You can print various images from their Timeline onto one side of your customized MOO card; on the other side, you throw in a tagline, Facebook username, phone number and website.

At Web 2.0 in 2011, 4chan's Chris Poole said that Facebook and Google were doing identity wrong. "Google and Facebook would have you believe that you're a mirror," he said, "but in fact, we're more like diamonds." Of course, it's not very easy to market multiple identities, so why would Facebook even try to do that? Exactly. Poole continued his talk about online identity, stating that Google and Facebook are "consolidating identity and making people seem more simple than they really are."

Unlike Facebook, professional-only social network LinkedIn has a clear purpose and vision: To connect you with other people in your field. It recently updated the CardMunch iPhone app, which scans business cards and connects them with the users' LinkedIn profiles.

The majority of LinkedIn users are in the high tech and finance worlds. Most people on Facebook use it to keep in touch with family and friends, not to network. But unlike LinkedIn, Facebook is what you make of it.

"It's clear that consumer habits of sharing business and personal information are evolving," says MOO CEO and Founder Richard Moross. "The lines between online social networking and offline business networking are not just blurring, but vanishing."

But are they really? And more importantly, will you buy a MOO/Facebook Timeline card?
