In a key paragraph of a brief Guardian article, Dan Gillmor implies that academics and other kinds of experts should have not an option but a professional obligation to write regularly and clearly for a wider audience than their workplace peers:

• Another is the value blogging brings to the creators when done right. Blogging has helped liberate academics from the publishing racket that does as much, in my view, to hide useful information as surface it. Its informal tone is readable, as opposed to way too much academic prose. Blogs can make sometime abstruse topics understandable for the rest of us who don't know the jargon; we just want to learn something. Lawyers and scientists are great examples of people whose blogging demystifies their worlds. If we could only read their writings in journals and the occasional op-ed column, we'd know much less.
