I just went through and checked out the site and hit a bunch of the links.. Honestly, with the nature of the data, there really is no reason to have more than the basics. Also, think of what Berkshire Hathaway is about and as far as maximizing everything that they can for the stake and stock-holders, it makes sense. Focus on the investment essentials, not the window dressing online.

I wish more businesses were oriented this way.
