It would get a better reception without the intro paragraph and if it were titled "an introduction to Metropolis Hastings." The post really doesn't even give you a taste of the most common MCMC algorithms, and what they are useful for.
For instance, sampling from complicated Bayesian models, and Gibbs sampling are the two most important things to introduce to roughly cover MCMC and those are in the paragraph he calls "bullshit" because he doesn't know the words.
