As much as I regret seeing Google Wave falling by the wayside, I have to say I do respect the clear and yet respectful language that Google uses to announce the end of this project. I don't remember seeing this so often ...
Official Google Blog: Update on Google Wave: "
Wave has taught us a lot, and we are proud of the team for the ways in which they have pushed the boundaries of computer science. We are excited about what they will develop next as we continue to create innovations with the potential to advance technology and the wider web."Google CEO Eric Schmidt gave more insight into why Google Wave was stopped:
"We have a pretty strong view on this," he said. "As a culture we don't over-promote products...we tend to sort of release them and then see what happens."
Schmidt boiled it down to a mathematical formula. A new product gets announced and gets a certain amount of traction. At some point, growth falls off the first wave of people finishes trying things out. Then, it begins to grow again. "The first derivative of that second growth is a high and accurate predictor of what will happen."
