That dashboard supported something like a dozen people over its lifetime. One person would start writing it, then quit, and be replaced by another person who rewrote it in their preferred language, and then the cycle would repeat.
It was a VC-funded welfare program for slackers and I miss it greatly.
What really made me mad was when we hired consultants and the contract would end, usually without much success because Twitter's problems were not normal problems, and then they would send us a fancy gift basket with our own wasted money.
Maciej, we are still waiting for you to ship the executive dashboard.
