This thread provides a wide enough sample population of people who have a problem with these services. Additionally, this population is getting bigger. I do hear friends and family concerned about facebook -even in the early days. Does grandma care? no. She doesn't need to. We just need to create replacements for these services that replace the need to use them (facebook and google for instance) to 100% satisfaction for those interested. Then we can worry about growing them. We don't need to worry about the entirety of mankind... yet. Startups 101
