'Controlled Serendipity' Liberates the Web

[Commentary] If someone approached me even five years ago and explained that one day in the near future I would be filtering, collecting and sharing content for thousands of perfect strangers to read — and doing it for free — I would have responded with a pretty perplexed look. Yet today I can't imagine living in a world where I don't filter, collect and share. More important, I couldn't conceive of a world of news and information without the aid of others helping me find the relevant links. Sharing has become a reflex action when people find an interesting video, link or story. Great content going viral isn't new. But the sharing mentality is no longer confined to the occasional gems. It's for everything we consume online, large or small.
