Based on the guidelines mentioned for use, it seems that HN is only welcoming to people that possess certain 'perceived' knowledge (or are able to construct really brilliant technical questions related mostly to the electrical/electronics, math/science fields (with programming being a subset).
So instead of calling it anything else, is HN simply elitist by design?
PS. If I say, only valid/intelligent responses welcome, does that in turn make my question elitist?
