Paprika: Voice is a Spice

To use voice in a compelling way, recognize that voice is a spice, not a main ingredient. Voice and other real time communications brings out the flavor in some other application, but it isn't the star. A compelling application starts with solving a real customer problem, and unless your customer happens to be a telco, carrying voice probably isn't the issue.
The issue is something else. We don't know the problems faced in other verticals because we've been so focused on the problems in ours. I bet you that if you spent just the smallest amount of time looking at transportation, or financial services or education, you'd find all sorts of places you could sprinkle basic communications into the mix to make it more delicious. Because we haven't done that, the food is bland and boring. You deserve better, and most importantly, customers deserve better.
