1. User generated content as hypnotic and addictive: watch and listen to Wikipedia being edited. According to the creators’ blog, the sounds indicate addition to (bells) or subtraction from (strings) a Wikipedia articles, and the pitch changes according to the size of the edit.
2. Facebook is not quite over yet — Pew finds that 94% of teens have Facebook accounts, and 81% report it’s the profile they use most often. Facebook’s deep integration via API and login mean that this traditionally fickle demographic may find it hard to detach from the mothership (even if their mothers are on it).
3. Millennial news outlet Policy Mic gets kudos for its viral success, driven by smart adoption of behavioral analytics. Policy Mic understands that serious content can still be shareable, and the difference between optimizing for social and search.
4. The role of social channels as a significant content distribution vehicle was underscored when a site outage compelled the New York Times to publish breaking news on Cairo via Facebook. If your organization is still treating “traditional” digital and social as different beasts, now’s a good time to rethink your approach.
5. Ready for the weekend yet? I’ve previously covered the banana slicer, but Amazon has compiled a most excellent list of its funniest product reviews.
