so i've never met the chap who does this blog (i think his name is Will), but i've been reading it for a while now. Don't let the post with pics of legos mislead you--this guy knows what he's talking about. In particular, his posts on parameter estimation and MC simulations are excellent. His writing style is unpretentious and patient (ie, not "see how smart i am" but "here's this fascinating subject that i really want you to understand") and in every post i've read on this Blog, he's got something interesting to say even for those who work in this discipline.
