Yes, Facebook has been a key stepping stone; but in terms of whether it’ll become a long term Internet node, forget it! It’s too messy, unstructured and it will never generate revenues to justify its valuation. Those of us involved with community based sites know how hard it is to extract dollars from advertisers. You need to be focussed and anal about giving advertisers ROI. Quite simply there is less than a billion dollars of ROI from Facebook.
