At one time I had contemplated building an app like grapevine. i.e. blind for India. Kudos to Grapevine folks for executing on the idea and actually building it. There was one wacky idea I had which I'll share. Rest assured it's wacky.
A company based/wide live chat for anonymous internal ranting. The dream was that the entire company would chatting and voicing their realistic thoughts during a boring ass all hands meetings.
Of course there are legal problems with this as chances are you might get sued etc etc also the problem of verifying people from an org without comprising on anonymity.
Anyway let me know your thoughts.
Cheers
