I really think this is the correct lesson to be learned from Twitter's troubles (not that we haven't said it here before): "away from the hilarity, Dave Winer's developing rssCloud and people are beginning to talk about Laconi.ca. The only model that makes sense is a distributed one: it's a fundamentally harder problem to bring down a decentralized network, because there isn't a single point of failure." Related: Valdis Krebs analyzes Twitter-style networks. "Twitter, Facebook, GMail and all other single site based services play with the Betweenness Paradox -- ultimate power/control when in operation, ultimate fail when not. Single point of failure. Brittleness, not resiliency."
