Swope offered more details on the new features:
After posting to Facebook via Mentions, you can now easily share updates, photos and videos to Instagram and Twitter.
Now you can add topics that you’re interested in — like other people and hashtags — to your Mentions feed. By adding a topic, you’ll be able to see public posts about that topic in your feed, in addition to posts that mention you. For example, if you’re an athlete, you can add your team or other players. If you’re a musician, you can add your band.
