I'd say that in addition to learning from failures, having the energy, resourcefulness, and courage to try enough times to gain the necessary lessons is also important.
Not to state the bleeding obvious, but isn't real life a little bit different to the internet? If I want to see which kickstarters have had a modicum of success, I just do a descending sort. It doesn't work like that in real life.
Didn't I just explain it? I can't do a descending sort of every store on my local high street based on their success so far. These things snowball on the internet because the sorting and quantifying process lends itself to viral snowballing.
