I remember liking it and then they turned into something(s) else and I'm pretty sure I remember not really understanding what they were supposed to be and I sort of gave up / couldn't figure out why it got so much media talking head attention after that and then ... I don't think I heard anything about it again.
The whole process of "Do a neat thing that isn't really profitable (or at least not a unicorn profitable), then pivot into something else / away from users." thing happens time and again.
Honestly I think I try / don't install as many apps anymore because of such things.
