When I was in 4th grade in the '80s, I wrote a letter to the CEO of Atari. I was a stockholder(maybe 5 shares, ha), and I was concerned that Atari could do a few things to make their games more enjoyable. I received a really nice letter in return that addressed my concerns, and a bunch of promotional material was included. In retrospect I wish I had written more letters and perhaps built up correspondence with someone high profile.
