I often get asked on the OpenTracing and OpenCensus projects, how they relate to each other, and how I feel about it.

TL;DR I believe that OT/OC are 1.5 projects, which should merge into one project. We collaborate on other efforts, and the differences are relatively small. In more detail: Personally, I feel the projects are very similar, with a shared goal of promoting tracing and monitoring by creating standard tools and interfaces for people to use.
