Criticism is good. Straw men are not ("your opinions and arguments on dbs are irrelevant because your blog fell over"), and being holier-than-thou about it only makes people stop listening to your actual criticism. That's why I think it's unproductive.

If you're stupid enough to think that blog software reflects on the contents of the blog, then you're likely not going have the critical thinking capacity to evaluate any of these criticisms anyway.
