Google Wave, yes. For as much as they pushed it and acted like they were confident, they bailed really fast. Google Talk, Google Code, Google Notebook, iGoogle. Various APIs for maps etc. Big pushes that never go anywhere like Google Books. Wasn't there Google shopping at some point? Or non-discontinued things that aren't really taken seriously: Google Plus, Allo, Google Scholar, any number of rebrands of their payment service. Lots of acquisition-shutdowns or just embarrassments like Nest. But more importantly, they just don't seem to actually have a strategy. Every few months we hear this is the future, and then that thing is never mentioned again. Or they announce a clone of some existing successful service and then don't seem to have any follow-through willpower. All these renames/migrations/rebrands usually come with breakage of the UI/API/functionality. It's irritating to actual users and feels sloppy to everyone who pays attention. However Google earned this reputation and however fair it is or isn't, it undoubtedly hurts new product launches. So the question is, how does Google throw off the reputation of being completely untrustworthy?
