Serialized Twitter "Articles" as Attorney Marketing?

While writing articles has always been a mainstay of attorney marketing, there may be a new way to publish one's articles in bite-sized chunks.  A recent post (http://www.techcrunch.com/2008/10/13/can-twitter-authors-capture-the-magic-of-lonelygirl15/#comment-2501076) at Techcrunch profiles writer Nikki Katz's use of Twitter to publish a fictional work entitled MyLifeIn140, which is the story of a 16-year-old girl who changes her world by editing photos.  Rather than using traditional publishing to disseminate the story, Katz sends out bits and pieces of the story through "tweets" on Twitter, which are limited to 140 characters.  Techcrunch notes that such publishing methods have been extremely popular outside of the U.S. (e.g., in Japan), where many bestsellers have been written using mobile phones.

Lawyers who have a sizeable following on Twitter could consider using the platform to "publish" short articles about topics of interest to their "followers."  Rather than drafting a new article, an attorney could take existing content and re-publish it using Twitter.  Doing so could establish and confirm a lawyer's expertise - via a new medium.  Twitter publishing could become a new tool in the world of internet marketing for attorneys . . . .

Any comments on whether such use of Twitter would be an ineffective means of online marketing for attorneys?
