PP,
I agree that with time JustDial would iron out bugs and operational challenges.
On conference call they mentioned that they do not want to follow discounting model. I find it hard to believe that a customer would care deeply for a bundled app compared to deep discounts and easy returns.
In non e-commerece spaces, I got highly focused apps with more options and a highly differentiated experience. I would be willing to do a 180 on my views on JustDial, if I can see a unique user experience from them. In most categories they are already too late. For example, Practo already has reached out to a significant majority of doctors in India or online grocery guys have achieved scale to neagotiate better discounts from brands.
