I have previously argued that large law firms should create firm-branded blogs (here and here). Fellow blogger Robert Ambrogi has an excellent discussion of the pros and cons of large law firm blogs. 

He opens with the observation that “as sure as thesis breeds antithesis, blogging’s popularity within the legal profession is drawing some to question its value, mostly with regard to marketing.” He cites and summarizes two recent pieces that offer different perspectives and offers his own views and conclusions.

For anyone at a large firm (or small for that matter) considering a firm-branded blog, Bob’s post is mandatory reading.
