Not everything on this list is there because it's 'legacy'. Read the descriptions carefully and the reasons for their presence (from the author's point of view) should become apparent.
I don't agree with everything he's written here but I do see his point of view and regardless of my disagreements found the article entertaining.
I guess devs working with the languages written would take offence easier (because just like everyone else, Devs can get stuck in their ways, too) but unless you are a narrow-minded sort or a Dev whose skill-set was recently developed into these languages I don't see anything here that would make you go 'stoopid artikkal!'
Give the man a break and go and write your own list. hell, post your alternative list here as a response and I'm sure it'd be well received.
