tomayto, tomahto, or also platform-status
Platform Status gives developers a cross-platform and cross-browser roadmap for browser features, from standardization and development to release. Not only a channel to raise awareness, it can also drive adoption and improve the vital feedback loop Firefox's platform needs to have with web developers. For most developers it will be a reference to discover and learn, but it has the potential to provide the entry points for radical participation on Mozilla's platform development.
Existing web compatibility references, like caniuse focus on cross-browser compatibility but don't cover un-released features and lag behind on features that already shipped. Major browser vendors (Edge, Chrome, Webkit) are publicising their own platform status with references to their bug tracking and bug owners. Similar to Platform Status' goal, Chrome tracks consensus/enthusiasm from other browsers using sources that range from bugs, to IRC logs to tweets.
Platform Status can send an open and clear message to developers about the state of Mozilla's platform, from proposals of new web features to release.
