Main problem of this list is that 30 is huge number. You can simply create Top 5 or 10 list of most influential programmers and place just A+ people on them, but there are no 30 A+ so you need to place "just" A players and there are hundreds of them. Another problem of this list is that they place also B and C level players and also non programmers (Jason Fried).
