11:21 < killes> seraph: unfortunately, the core blog module still requires its own
                dedicated blog content type
11:21 < killes> seraph: what you could try is to create a link "add special blog type"
11:21 < killes> seraph: the link would be /node/add/blog/special
11:21 < killes> seraph: and then in the form_alter hook, you remove the taxonomy fields
                if the fourth argument isn't "special"
