Ask HN: Abandoned/dead projects you think died before their time and why?

Pivotal Tracker ; Users loved it, it had an excellent model for tracking work and limiting work in progress on software projects. There is no real good alternative and the usual suspects for tracking project work are horrible in comparison.

I don’t know about that. My employer was all in on Pivotal and we used it for several years. Then one day a dev stumbled across Linear, we all tried it, and switched the whole company within a month or so.
