One of the major silent qualifications for posts like these are "if you read/speak English and have a standard keyboard layout".
Which is sad. I had an Egyptian friend who told me he had to use Linux in English because the Arabic support wasn't quite there. This wasn't a problem for him, but would have been a non-starter for his family.
He tripped in front of the chickens while gathering their eggs, destroying all their hard work, and now they look at him in disgust and disappointment.
And that's why you never keep all your eggs in one basket.
