Why are there so many law blogs?
Volokh Conspiracy, Instapundit, How Appealing, Three Years of Hell, The Kitchen Cabinet, etc.

Don't get me wrong - I think the writing on these blogs can be good to excellent, which is why they are linked to. But is there some reason why so many of the blog writers happen to be lawyers, law students, or law professors?

Yes, I am aware that every poster on this blog is a law student as well.
