Sergio Lub was doing social networking long before facebook or anything in that ilk in 1997. His network, Friendly Favors, has over 50,000 members, but needs to migrate to a more modern platform if it is progress. Faceboook and the barter networks have a damning deficiency, in his opinion, which is that they fail to capitalise or value trust. Ebay does trust, but ebay isn't actually about relationship building or barter, and the trust is not based on relationship, but only on the trading experience - it is completely impersonal, and no credit is extended.
