If the rest of us used Facebook like the Northlanders...

Hey Steve - I'm itchy for Facebook to truly expand beyond it's college-kid demo here because it trumps the other networks. The interface is clean. It's not too flashy or too bright, and I'm not bombarded with ads. I'm posting a guest post on my blog today that my intern wrote - we worked it out over our "walls" on Facebook. It's the fastest way to find her and anyone else I know under 26.

One thing I wonder about, though, is whether these networks will change and expand to allow for different tiers of friends. I'm really wishing right now that I could have two tiers of buddies - colleagues and friends, say - rather like I do in life. They could perhaps see different things about my profile. I don't want to see a system like this imposed from the top - I don't think that would work anyhow. We'd eventually just invite everyone into "friends". But in that online behavior mimics offline behavior, I wonder if natural adaptations to demarcate these separations will eventually pop up. On MySpace, for example, I'm a member of "Mike Zeimer" and also "Mike Zeimer personal friends" - two different profiles.
