I expect many readers to be following the ongoing debate, prompted by a poll run by Leiter last week, on the (presumed) effects that blogs have had for professional philosophy, both at the level of content and at the level of ‘issues in the profession’. (Roberta Millistein weights in at NewAPPS, and I agree with pretty much everything she says; another summary at Feminist Philosophers.) Now, there is a sense in which I am personally not in a good position to have an opinion on this, simply because I haven’t been around long enough to know what it was like before, and thus to be able to draw an informed conclusion. But I can say that my very process of becoming a professional philosopher (not so much content-wise perhaps, but in terms of deciding on the kind of professional I wanted to be) was considerably influenced by reading in particular the Feminist Philosophers blog. Also, I won’t deny that my career as a whole has tremendously benefited from my blogging activity at NewAPPS and at M-Phi, both in terms of the opportunity to discuss my ideas with a larger number of people than would otherwise have been possible, and (more pragmatically) simply in terms of increased visibility and reputation.
But obviously, my individual experience (or that of other bloggers) is not what is under discussion presently; rather, the question is whether blogs have been good for the profession as a whole. This, however, is obviously a multi-faceted question; it may for example be read as pertaining to the quality of the scholarship produced, to be measured by some suitably ‘objective’ criterion. (As a matter of fact, I do believe that blogs have been ‘good’ for philosophy in this sense, for reasons outlined here for example.) But it may also pertain to the overall wellbeing of members of the profession, in which case the putative effect blogs will have had could be conceived of in terms of a simple formula: for each member the profession (I is the set of all professional philosophers), estimate the net gain (or loss) in professional wellbeing by comparing their situation before (wb) and after (wa) the advent of blogs; add it all up, and divide the total by the number of members considered.
