Twitter announced in a blog post today that it’s adding a new capability to its Moments feature on iOS and Android. While Twitter Moments originally supported content like photos, videos, Vines, and polls, publishers can now added add links to Moments to continue telling their story on their own website.

Facebook has today unveiled a new app called Moments from its Creative Labs division that makes it easier to exchange pictures amongst friends who were together at an event or place, all documenting it through their own photos. Here’s how Facebook describes the problem they’re solving:

It’s hard to get the photos your friends have taken of you, and everyone always insists on taking that same group shot with multiple phones to ensure they get a copy. Even if you do end up getting some of your friends’ photos, it’s difficult to keep them all organized in one place on your phone.

Through the use of location and facial-recognition data (both areas where Facebook has invested heavily), Moments groups photos together and then asks if you’d like to share them with the people it has recognized, and vice-versa. It’s very reminiscent of the now-defunct Color, although that app was more real-time and ephemeral (Moments allows you to collect and sync photos with friends after an event is over), and wasn’t integrated closely with Facebook’s 1 billion plus user base.

It’s available now in the iOS App Store and on Google Play, so you’ll be able to share with your friends even if they’re on a different platform.
