I felt it quite underwhelming, until I realized it only looked at a handful of companies. Somehow only three of Microsoft board are on other boards? Wow, how puritan of them! Ah, not quite...
I'm with you - it would be better with more data (and the creator has stated he wants to expand to 500 companies, apparently that used to be the number prior to the most recent update which was a while ago).
It's the writeup he has in the "why" section that blew me away. A very sober and deep analysis of why we are where we are and what might be done about it.
