No doubt you're right. I guess it's just a generational thing. I hear Google, Amazon, iTunes, and I see immediate value. For some reason, even though I'm aware of all (or at least most) of the arguments that place value in Facebook / Twitter etc. I still wouldn't feel comfortable investing in it. I'm probably dating myself pretty badly, but they look fluffy to me.
