Exactly. If it replaces anything, it's because it is more efficient at it. This is all anecdotal, I know... Since Facebook, my email inbox is almost devoid of "RE:RE:FW:FW" broadcast messages.

I still use my phone a lot, but spend less time telling people how great (or not) my weekend was. If they want to know, they can look. If they want details, they call and ask.
