> But what's the advantage of Facebook over email and/or texting? This is anecdata but among my friends, e-mail addresses and phone numbers tend to change more often than their Facebook profiles. I know people all over the world, but out of all of Facebook connections, I probably only have accurate contact details for 20% of them or less. The contacts I interact with most often are obviously in that bracket, but many of those I talk to once a year or less are probably not. Case in point. I'm currently planning a trip, and while on a previous trip to the same destination I made a couple of friends there. I have a phone number to one of these contacts, but it's out of date. However, we're also connected on Facebook so I sent them a message their to let them know I'll be in their vicinity later this year. For better or worse – and this is obviously my personal context – Facebook is the best mostly self organizing contact list I've ever had. I couldn't care less about the wall, or liking things, or whatever you had for breakfast, but as much as I hate it it's the only stable way I've been able to keep in touch with all these folks that I want to keep in touch with. If or when I no longer want to keep in touch, I just prune them from the list, and likewise I get pruned from other people's lists whenever they feel we're "done." I don't want to use Facebook, but e-mail and phone simply doesn't solve my problem of keeping an up-to-date contact list. They also don't work simply because I can't easily look up a contact and connect with them, because there's no global phone or e-mail book. I'd love to use something else, but fact of the matter is that everyone I want to keep in touch with is there, and until they are also elsewhere in a list that organizes itself, I feel obliged to use it. :o(
