This week in social media platform changes

What did I miss this week? Let me know in the comments!
  1. Big shift for the social media darling Snapchat: a new feature "Memories" introduces a way of saving and sharing old snaps in a private archive inside the main app.
  2. In another massive shift to the core of Snapchat: As part of the new Memories feature, you can post pre-produced photos and videos to Stories.
  3. This.cm, a social network where users share just one link a day, launches a standalone app.
  4. As Facebook shifts to video, the platform makes viewing easier for those with limited Wifi or internet connections: making videos downloadable for offline viewing.
  5. Instagram insights are now available on Business Profiles, illustrating how posts are performing and providing details about demographics and activities of your followers.
  6. Facebook adds the ability to like, comment and share Instant Articles – and on media that appears within articles.
  7. Twitter is testing two new features for customer service: The ability to feature a time of day when the account is most responsive to mentions; and a tab showing "featured tweets" curated by an account.
  8. Pinterest updates its advertising strategy to expand keyword search (meaning, you can buy space on Pinterest that surfaces with specific keyword searches, as you can with Google) and interest-based targeting.
  9. Facebook is testing a "multilingual composer" that translates posts into one of 45 languages.
