I'm no expert on W.Buffet, but I've read a lot about his life and investment principles. He owns companies like Sees Candy, and although I love a good ol' box of Sees around the holidays (and I admire their company), I can't help but associate my Grandmother with their products! What I'm trying to say is that Buffet is, for me, is a generational investor - the best of his generation or even (arguably) the 20th Century, but definitely of my Grandmother's generation. He's remained incredibly relevant to a large extent based on his investment principles, looking for value bets and investing (or rather, buying) for the long run. I, for one don't think that Facebook is overvalued at all, if you think about it's revenue potential, but Buffet invests in undervalued companies, not over-promised ones that have yet to reach their potential. Facebook's egg hasn't hatched yet in a way that justifies their evaluation, but it's easy to reconcile Buffet's investment principles with more speculative investors that see Facebook as a safe bet. Finally - it's not hard to image a few different models that could outpace or even replace Facebook's main product proposition (providing a common, social "space"). So not many investments remain secure over a very long term. That's the brilliance of Buffet.
