Ask HN: What is the best tangible benefit of social networks?
What is the most compelling tangible benefit that you can think of Social networks like FB or Twitter.
I did. Not only did I like this person, but ridiculous disco music is very much my idea of a good time! We had a blast.
Maybe that evening happens without FB, maybe not. FB offers a way to ping your whole social network and see what comes back. Sometimes nothing -- which can be a downer. But sometimes it works, and when it does it's awesome.
