Yeah that was a profoundly underwhelming article, especially for an "expert". You would think Maria and Matt would set a higher standard for contributors.
It's an interesting idea, and I totally agree with it, but the article seems like a long shower thought. I'd love to see more evidence that a list of links is actually the right solution for Berkshire Hathaway customers. I bet it is, but the author is making a big assumption that what exists works for their customers because Berkshire Hathaway is successful.
