We referenced the 2016 Stack Overflow Developer Survey a couple times this month, using its findings to back-up some claims. The survey is filled with knowledge and trends about top technologies and pay rates, and some fun stats like preferences over Star Wars and Star Trek.
One set of charts we found particularly interesting is about the most loved, dreaded and wanted pieces of technology. It seems the most loved are Rust, Swift and F#, while developers on Stack Overflow dread Visual Basic and WordPress the most. More importantly for an IT contractor looking to keep skills up-to-date is the most wanted technologies, where Android, Node.js and AngularJS top the list.
