I know everyone is linking to they rule, but I’m not going to let that stop me from pointing to it from here. Rarely do I find a new site that’s truly a useful research tool, but they rule is just such a site. Pick just about any big company and start expanding from there, and you’re bound to see something that will interest and surprise you in no time. For example, I clicked on Berkshire Hathaway, and discovered that the only other board Warren Buffett sits on is Coca Cola’s. Who else is on KO’s board? How about former Georgia senator Sam Nunn. What do you know? He’s also on the boards of Dell Computer, General Electric, and Texaco. No wonder he never ran for office again after retiring from the Senate. It would be helpful if the site added more companies though. Some biggies, like Sun, are not included.
