I picked up on the same point because the numbers just sounded too stupid low not to look into, I should have checked the comments here first.

I didn't pick up on the editor of Kernel and the author of the post being the same person - something that should be disclosed.

Explains why they didn't link to the posts!

Shame because in the previous thread about tech blogs The Kernel was mentioned as a good, new alternate source. Turns out they are not too different ..
