This is a pretty touchy subject a lot of older miners don't like to talk about. I think everyone is afraid of the new pizza issue happening with higher priced items down the line, thus holding on to them for a while longer than they used to.
True. Gavin Andersen was very uncomfortable when asked about "bitcoin faucet" (interview: Triangulation 103).
Bitcoin fauced used to be the largest bitcoin giveaway in history. It was a script that send you free bitcoins to play around with. At the beginning it used to give away 5 btc to every visitor (first determined by IP and Bitcoin address, later by Gmail account). This value decreased over time to mBTC.
It appears that Gavin Andersen gave away total of 10'000 BTC, an equivalent of 1'300'000 USD today. (if I remember it correctly...).
Of course it wasn't all his money, he used to get donations to do this... but still.
