The whole problem with the deletion process. Not just on the English wikipedia, is that people who do not know anything about the subject get to judge. So many times you will see reasonings like ... I do not know about it so it isn't notable ... . I know it is impossible, but ideally only people with knowledge about the subjectarea(s) that the articles topic would fall under would be the ones who should judge these things. Not everybody. But unfortunately this will never be the case.

I'm afraid I've seen this also. Non-US articles appear much more likely to come up for AfD.
But it's not just geographic. The Maui Cluster Scheduler actually came up for deletion with a result of "no concensus". This is a piece of software that is an integral component of high performance clusters the world over. One voter apparently wanted it deleted because it was not useful for his home PC. At the very best this is parochial.
I'm glad this topic has come up for discussion. IMHO the entire deletion process (including speedy deletion) needs to come up for review. It's too easy for articles to come up for AfD.
It was interesting to sit in a Greater Toronto Area Linux User Group meeting recently and hear people list many (IMHO) reasonable articles that had been deleted. This was a spontaneous discussion. I bet if so many people in Toronto are concerned about the deletion process that we aren't alone.
