I am entering the Pay It Forward Contest regularly and the people I feature receive a SBI share each, even if they aren't picked as winners.
I also try to do a weekly roundup of undervalued artistic works and put them to a voting. The 3 picked by the community receive a SBI share each, at least. If the post generates enough for more, I buy them more than 1. The first week I distributed 7 SBI shares. The second was not so good, it was just enough to give a SBI share to each of the 3 winners.
