That link is a great example of why I stopped using stack exchange. The OP asked a question about tiling spheres with pentagons and the third response is basically "you can tile a sphere if it's not a sphere."

I had analogous experiences every time I asked a question there. One would ask a very clear question like, say, "how do I print to stdout in C?" And the first or second answer you get is inevitably about taking input from stdin. Or polymorphism.
