I've been wondering for months now why something like that doesn't exist. Here are some comments I wrote on that topic (or a closely related one): https://news.ycombinator.com/item?id=12139112 https://news.ycombinator.com/item?id=12139112 https://news.ycombinator.com/item?id=12390514 https://news.ycombinator.com/item?id=12390514 As mentioned in some of the comments, there are probably some technical hurdles (keeping score of every edge in the network), but can't they be overcome?
