Top 10 JavaScript - But where is ExtJS???

Someone out there thought to himself ok ... lets see what JavaScript framework exists out there? And he come up with a list but w/o ExtJS nor YUI. I don't get it, how can he miss YUI and ExtJS??? Or did he get to a point when he thought, well I have 12, top 12 doesn't sound so good ... lets drop this and that one :)
