I find it concerning when project developers don't seem to know exactly WHY the product exists or how it compares to competition on the market.

If I'm spending a lot of time working on a product that has a clear competitor(s), I'd expect to know exactly why my product is going to be better than those competitors (ie. in which ways), and what their weaknesses are.

A lot of open source developers go to great lengths to avoid admitting that anything competes with anything else. I don't know if it's just conflict avoidance, rationalizing failure, or what.

I can spend hours and hours to explain why Zeppelin is good and what is different feature compare to the other.

for example, Zeppelin has pluggable architecture so it does support not only scala but also python with built in Spark integration. Zeppelin not only support data exchange between scala and python environment but also SparkContext sharing for spark cluster resource utilization. It's got ability create rich interactive analytics GUI inside of notebook. It's got customizable layout system, and so on..

But I wanted to address more fundamental difference. Most competitors are opensource project. And as a opensource project, how community works and project direction are the most important things. That'll make huge difference in the end. And i think i explained and compared them.
