Instagram limits sensitive content, Twitter podcast space, and Instacart influencers

Instagram is limiting sensitive content for new users under the age of 16. Those accounts will have the most restrictive setting by default, aimed at shielding teens from inappropriate content like sex and violence. Instagram will recommend that existing teen users also make the switch.

Twitter is testing a new version of its spaces tab that will offer podcasts. The tab will include titles from Vox, NPR and other sources. The podcasts will be broken down by category and be featured alongside similar spaces.

Some news from Instacart that might inspire your picks at the grocery store. The new feature will use influencers to make your shopping list. It’s called “carts” — and will display items on celebrity shopping lists. Rapper Lizzo will be one of the first, appearing in an ad showing her using the app while sitting in her bathtub.
