This is pretty much the spirit of Google too, start a service, have no users, discontinue service. The problem with this is that most of these ideas don't work because they are usually too early for their time. Which is quite stupid when you think about it retroactively. If they kept going at it, Google could of had a successful social media platform (Dodgeball), they discontinued the v1 of Instagram, Picasa and they could of been Foursquare with Hotpot... Now the question is was it a good idea to stop these and maybe save a couple hundred K a year ? Retroactively, of course no, but I would argue that even at the time it was a bad idea, why waste RnD when you can easily afford to keep it going for decades without it generating any profit... Move fast and break things but don't trash them...
