Crowdfunding is an interesting subject. I have donated to St. Jude's Hospital and the Red Cross, which had had successful online campaigns. I didn't know the term for these campaigns.
I think it is a concept that can do so much good and help people during natural disasters and things of that nature. It is certainly more fun than a telethon --- plus many people are connected via Facebook, Twitter, etc.
It is an immeadite way of receiving funds, and based on the readings, I would be more inclined to participate and find out about a campaing online, than if it was advertised on TV, radio or other types of traditional media.
