I dont think it would really work, there isnt much you could do for an internet stranger than give money. pretty sure swapping book sites etc already exist. so

I dont think it would really work, there isnt much you could do for an internet stranger than give money. pretty sure swapping book sites etc already exist. so it seems like it would just be swamped with people wanting someone to randomly paypal them money, along with a sob story. plus as mentioned in the comments, it kinda games the idea of karma if you have some badge pronouncing how "good" you are. I think random acts of kindness are best done off the internet. I think what might make a cool site is somewhere for people to post random acts of kindness people have done for them. no real point to it, just feel good stories
