According to a recent count by Daniel J. Solove of George Washington University, 130 law professors have active blogs. David Chalmers of Australian National University lists 85 philosophy professors or Ph.D. students with blogs, mostly oriented to the discussion of philosophical issues. In both of those disciplines, those who don't either blog or read and comment on others' blogs are cutting themselves out of an increasingly important set of discussions.

…Why are so many academics beginning to blog? Academic blogs offer the kind of intellectual excitement and engagement that attracted many scholars to the academic life in the first place, but which often get lost in the hustle to secure positions, grants, and disciplinary recognition. Properly considered, the blogosphere represents the closest equivalent to the Republic of Letters that we have today. Academic blogs, like their 18th-century equivalent, are rife with feuds, displays of spleen, crotchets, fads, and nonsenses. As in the blogosphere more generally, there is a lot of dross. However, academic blogs also provide a carnival of ideas, a lively and exciting interchange of argument and debate that makes many scholarly conversations seem drab and desiccated in comparison. Over the next 10 years, blogs and bloglike forms of exchange are likely to transform how we think of ourselves as scholars. While blogging won't replace academic publishing, it builds a space for serious conversation around and between the more considered articles and monographs that we write.

…What advantages does blogging offer over the more traditional forms of academic communication? Blogging sacrifices some depth of thought -- it's difficult to state a complex thesis in the average blogpost -- but provides in return a freedom and flexibility that normal academic publishing can't match. Consider the length of time it takes to publish an article in a peer-reviewed journal. In many disciplines, a period of years between first draft and final publication is normal. More years may elapse before other academics begin to publish articles or books responding to the initial article. In contrast, a blog post is published immediately after the blogger hits the "publish" button. Responses can be expected in hours, both from those who comment on the blog (if the blog allows them) and from other bloggers, who may take up an idea and respond to it, extend it, or criticize it. Others may respond to those bloggers in turn, leading to a snowballing conversation distributed across many blogs. In the conventional time frame of academe, such a conversation would take place over several years, if at all.

…Once you get used to this rapid back-and-forth, it can be hard to return to the more leisurely pace of academic journals and presses. In the words of the National University of Singapore philosophy professor and blogger John Holbo, the difference between academic publishing and blogging is reminiscent of "one of those Star Trek or Twilight Zone episodes where it turns out there is another species sharing the same space with us, but so sped up or slowed down in time, relatively, that contact is almost impossible."

…Most important, the scholarly blogosphere offers academics a place where they can reconnect with the public. The links between academic argument and wider public debates are increasingly tenuous and frayed. It's far harder than it used to be for academics to become public intellectuals (not that it was ever very easy, or very common). This has malign consequences, not only for the quality of debate on both sides of the divide, but also for public perceptions of the academy. It's also a source of considerable frustration to many academics, who either believe that their academic expertise could be valuable to a wider audience, or resent the distorted public perception of what they do. Blogging democratizes the function of public intellectual.
