There are incremental/larger/easier improvements and then there are populism "improvements." The one tends to amplify the other. Facebook was incrementally better than Myspace at first, and then became more popular and much better. Myspace was much better than Friendster. It's an evolutionary model where some improvements are made, some features are lost, and specialization meanders. I think the transition point is when incremental improvements amplify themselves to the point where they are both way more popular and way more efficient than what came before.
