Some highlights I saw -
* SF is center of the tech world. Next biggest is just around half of its size. (not withstanding HN bias).
* Approx 25% jobs allow visa sponsorship
* HTML, Python, .Net overwhelmingly dominates everything else.
* Reduced interest in databases, SQL, Obj-C, Java
* No TensorFlow or PyTorch in demand
* 90% jobs in development/software engineering, 10% in management and misc.
