"So what are the lessons that Digg has to teach Twitter? One is that even pioneering services, whose founders appear on the covers of leading business magazines, can be overtaken by events, and by other services that don’t even exist yet. Yes, it’s true that Twitter is supposedly worth $10 billion, and is much larger than Digg ever was. But that lesson still applies (as MySpace is well aware). It’s easy to grow complacent and inward-looking, and thereby miss the warning signs of declining growth, or be too slow to react."
