You go and tell that to all the people I know in real life that use facebook - the mothers in the school playground for example.

Facebook is so big most of its users don't care about any of that stuff. For them it has one simple function - its a good way to interact with friends and family.

These are people who probably couldn't program the VCR to record a program in advance, who shrugged their shoulders when our (uk) government left all their children's records on a train, whose technical knowledge is minimal.

Facebook is doing just fine - just techies who worry about the details who are going off it. For the mainstream it works just fine.

(and as an aside - one of the weirdest things ever is hearing people who would have thought that me and my mates playing D&D when we were younger was geeky and strange - talking about things like farmville in just the same way)
