I think you're underestimating Facebook's social importance. Sure, your friends won't hate you, it won't be the end of the world, but there is a palpable sense of disconnect.

And there are more people who rely on Facebook for social connection, than people who rely on Google for business and finance (especially if you're talking about the under-25 crowd).

I believe your claims but is there any evidence to back it up (and is that possible on fuzzy metrics such as palpable sense of disconnect)?

From your other comments I understand you are from the US and I guess its a wholly different matter across the pond, but I for one cannot reproduce these effects here in Germany. Sure, most -- rough estimate: all -- of my contacts do have accounts on various social networks (me included) but we have never critically relied on it. It never gained quite as much traction as I always hear from Facebook.

Yeah, I think it's definitely different in the U.S. than Germany, regarding Facebook's hegemony. Hardly anybody uses anything else here.
