For an amateur's blog post in 2009 to call Altaic theory utter horseshit would been rather hubristic to begin with, and moreover, not even the point. The Altaic hypotheses were higher-profile proposals that happened to include common origin for Japanese and Korean. Even dismissing the former, the latter is not exactly out of consideration.

And, as the post points out, the whole line of argument is a curiosity that has little concrete bearing on the fact that the two are very similar from a learner's perspective.
