Do you recognize the names Robert McCool and Guido van Rossum? You might not know the names but they invented some important technologies that HN people use and respect (the original Apache server and the Python programming language, respectively). It would be hard to relate to a story that said "Robert McCool denied US visa" or "Guido van Rossum endured US visa hassles".
