Well. Sometimes, you can only best solve problems you understand. And those that you understand best are usually the ones you experience yourself. Many of us have the luxury of being healthy and well-fed, so that's not the problems we focus on. And were this written in 2004, would you have said social connection is adequately addressed by Friendster and MySpace? Just as Alta Vista was not the last word on search (nor is Google for that matter), Facebook is not the last word on Social Networks. I think there's something to be said, however, about digging by following your own sense of curiosity and intuition about good problems to solve, instead of seeing where everyone else is digging and just digging there. Use your noggin and explore. If it happens that no one else is digging there, so be it. And if that's what the OP is encouraging, then I'm all for that. But I don't feel there's a need to discount the current range of problems being solved.
