In my trevails on the Internet recently I ran across a site that gives a valuation of your web log.  I found myself on a site run by a guy named Dane Carlson, which talks about business opportunities. He created an applet using a Technorati API that calculates the value of each link to your blog. Just type in the URL for your blog, and it will return its overall value.  Since so many law firms have blogs (or as we like to call them, blawgs), I thought I would mention it here.  I do not know how accurate it is, or how well it shows the value of your blog (which can be fairly subjective and case specific), but it is worth checking out.
