Unfortunately there is a LOT of big bragging over donations and then very little follow through. It's nice to see someone actually DO something about it. I'm sure the people who have organized various events, auctions and collections for causes over the years have tons of stories about the phonies that never paid up.
My new motto this year is: PUT UP OR SHUT UP
I know of one webmaster a few years ago who did one of the Adopt-a-Kid at the holidays thing and thought that all he had to do was buy each kid 1 gift. I explained, "this IS their holiday - everything you buy is ALL they are getting." Still, he only sent one item. I heard through the grapevine that the people organizing the charity made sure those kids still had a good holiday and "made up" for what this louse didn't do.
Participating in that charity led us to adopt a whole family here locally, the kids really get into it and I'm glad that they are learning to NOT be like that guy who sent 1 gift to his kid.
Point is.... every little thing you do - although it may seem small to you - HELPS. So don't let the losers get you down. If you want to contribute - that's awesome. If you don't or have an alternative charity you would rather give to, that's cool too. Giving is a very personal thing.
