I read an interesting post from Dennis Kennedy detailing the most common mistakes made by legal bloggers (and bloggers in general).  Check out his post here, but here is a short version of his list:

• Launch a blog without trying to understand the blog culture or the blogging world.
• Don’t post on a topic that you clearly got from another blogger without crediting that blogger for pointing out the link, article or resource to you.
• Falling for the common advice about getting reciprocal links and treating prominent bloggers as if they offer a free search engine enhancement service.
• Being overly-familiar with existing bloggers or taking pot-shots at existing bloggers to make a name for yourself.
• My Pet Peeve: Being a New Blogger Who Lectures People About the One True Path of Blogging
• Think Carefully About This Anonymous Thing.
• The Biggest Mistake: Not Using Full Text Feeds in 2005.
• Bonus: Not Treating Your Blog Launch Like the Launch of a Publication.

Good points for anyone considering blogging!  Thanks Dennis.
