Google has failed multiple times at launching social apps. Is there an equivalent series of Apple failures from being too controlling? If not, what makes this a blindspot?
The first 3 are the same thing and aren't even social apps.
But, iTools was great when it was around. Way ahead of its time and free! When they went to subscription model I think most early adopters had a hard time justifying the price when you could get hotmail for nothing.
