Because I see this, and I think, "Wow, that's cool. I want to listen to some of these." And it just makes so much sense that my computer should be able to compute a hash of that archive and seed it for others, at least as long as it's on my machine.
It makes me think about how recently, we've collectively embraced an abstraction of what it means to share content online, because of the way that social media works. There's the actual transfer of bits, and then the newly-formed social-media advertisement that says, "I endorse this content."
Isn't it a little fucked up that most (all?) of our social networks don't allow for you to share content to other people without implicitly making a statement about it?
Is anyone aware of someone attempting to create social browser history? I already share it with Google. It might be fun to share it with friends, too.
eg: See that a coworker and I both have visited that stackoverflow post a dozen times, or see that my highschool teacher also read that article, or see that my friend listened to the new Radiohead album.
The problem with Facebook, and even with Twitter, is that every single post becomes a statement. I think this is why snapchat is filling a niche -- maybe it's actually not interesting because of impermanence, but maybe it's about the expected notability of each post. On Twitter or Facebook, your posts end up in the feed of someone else, so there's a pressure to not shitpost.
Snapchat doesn't really have that. You can post dumb shit to your story all night, and people just will get tired of looking at it and go to someone else. No harm done.
I wonder if social browser history could work for the same reason. Unfortunately, I think it'd be a hard sell. People see their browser history as private, in spite of the fact that their browser is full of third-party tracking cookies. You'd never get people to download an addon.
