thanks for the feedback, I agree having showcases is crucial for showing what can actually be built with Wasp.
We ourselves built a copy of Medium with Wasp - feel free to see it deployed here (https://wasp-rwa.netlify.app/) and check the code here (https://github.com/wasp-lang/wasp/tree/master/examples/realw...)
For the super simple example with less code check out TODO app built with Wasp: https://github.com/wasp-lang/wasp/tree/master/examples/tutor... (check out main.wasp and then the code in ext/ folder)
Hope this helps!
