1. Now that we’re all shooting more photos and videos than ever before, Dropbox is hell bent on storing them for you. Dropbox knows there’s a high switching cost for moving all your personal stuff (hassle, trust) so they’re making it easy and appealing to store and share, particularly via mobile. And yesterday Dropbox purchased iOS photo app Loom to continue the offensive.
2. This week, Twitter took a page out of Facebook’s monetization playbook by adopting app install ads. With a heavily mobile user base, Twitter provides an appealing audience for app creators looking for new users. Here’s hoping this proven ad revenue model shores up Twitter’s languishing stock price.
3. Hunter Walk illustrates how context matters when serving up recommendations for end users. When YouTube recommended videos to users, the interface explicitly told them why: e.g., “because you watched these puppy videos, we’re showing you this kitten.” As a result, users were less likely ignore the recommendations — and consumed more video.
4. But what if you don’t want your online behavior tracked, for relevant video recommendations or anything else? The Atlantic cites research from Zeynep Tufekci on emerging user behaviors, from passive-aggressive subtweeting to active hatelinking, that regular people are adopting to remain invisible to the algorithms that track online behavior.
5. Also filed under “what your social networks now know about you,” Facebook has launched Nearby Friends, a way for you to find out who’s close by. The technology is based on Glancee, a startup Facebook acquired back in 2012. Needless to say, early messaging is all about user control and privacy settings.
