Personally, I think that web technologies are on the rise lately. Cross-platform also gains a lot of popularity, which might be a helping factor.
Web Technologies are open, they are always the same code with an overload of interpreters available for every platform out there. Just write the code and distribute it - anyone can use your app.
All those technologies are rather easy to learn and use. Compare using Electron to C++ for the mentioned use-case...
As a result I think that most people use web technologies lately which makes platforms like Hashnode and Stack Overflow mainly serve web technology related content.
While I do say that I am mainly a Full Stack Developer, I also enjoy playing around with OpenGL and Vulkan, which lead to lots of C++ development. If you need performance, nothing beats a compiled low-level program. But still, I use web technologies for things like the GUI.
