I think 18+ is a poor demographic group for this kind of survey. Here's my unfounded guess about the actual results: * 18-39 -- few people think it's a fad. *

I think 18+ is a poor demographic group for this kind of survey. Here's my unfounded guess about the actual results: * 18-39 -- few people think it's a fad. * 39-60 -- many people think it's a fad. * 61+ -- most people think it's a fad or don't get it. Lump all the groups together and you get 45% believing FB is a fad. I know I'm stereotyping horribly, but I can't see a lot of legitimacy in a survey that clumps everyone together into one big group when the subgroups probably have wildly varying opinions.
