1. Anyone who has ever clicked on a search result only to land on an article stub generated by a content farm will be glad to see this latest Google tweak. This update highlights up to three in-depth articles in the right column, pointing users toward deeper content (and perhaps directing their eyes toward the ads). Big opportunity for publishers of high-value, evergreen content.
2. 72% of U.S. online adults now use social networks, according to Pew. Breakdowns include slightly more women than men, and Hispanics represented more than African-Americans more than white, non-Hispanic. Retailers take note: adoption rates for adults 65 and older have tripled over the past four years.
3. A good example of how great content strategy combined with optimizing an existing technology can yield significant returns: Zach Seward on Quartz’s email strategy just as their daily brief expands to weekends.
4. Boston’s Here and Now covered Silicon Valley-funded Watsi, a startup crowdfunding medical care. This approach raises ethical questions, as well as potential positive implications for nonprofits looking to put a face on unrestricted giving.
5. In yet another take on mobile, visual storytelling, YouTube founders Chad Hurley and Steve Chen launched the Mixbit video app for iOS. There’s a collaborative element to the storytelling and some solid UX to make recording and editing less daunting.
