Thanks for the suggestion, but I don't really want to generate extra writing commitments for myself. I can use this journal to post what I want when I want, without feeling any great weight of expectations about whether I do so or not. But if I were to post in a more explicitly professional manner, I think I'd feel obliged to put more effort into producing regular posts of the requisite standard. I'd rather save those efforts for actual publications, and keep my blogging as a leisure activity.
