If you are considering stating a blog to market your practice (and I think it is a good idea), take a look at Dennis Kennedy’s post over at Between Lawyers where he put together 10 frequently asked questions you may want to look at before making a decision.
I don’t think there is anything overly daunting in his FAQ’s responses, but he raises some very good points on whether or not to blog. But, don’t stop there as there is tons of information out there, and of course his links to other lawyers’ blogs will be helpful to you. I concur in his suggestion of seeking the help of Kevin O’Keefe at Lexblog. I used him to create this blog and have been very pleased with all aspects of his work.
