Last Friday, Facebook relaunched the Comment View for photo albums, which displays photos at roughly half of full-screen and sorts them by those most recently commented on. Users can switch from Grid View to Comment view with a switch in the top right of albums.

The feature will be especially helpful to Page moderators who otherwise had to sort through notifications about feedback or look at photos one by one to moderate comments on their photo albums.

The team responsible for reviving Comment View, news feed engineer Dan Schafer, Photos engineer Nathanial Roman, and commerce team designer Brynn Shepherd told us the feature was developed as a Facebook Hackathon project. Facebook used to provide the Comment View for albums, but removed it last year as part of a simplification of the Photos product.

The team, who were originally Facebook interns together, heard complaints from users and friends about the removal of the Comment View, and also wanted to use it themselves. So they built the new iteration from scratch at one of Facebook’s internal Hackathons where employees are encouraged to work on projects they think could benefit the company, even if they’re outside their specialty. Their interest and complementary skill sets made the Comment View an “ideal Hackathon project.”

Now admins can use the feature to quickly see what people are saying about the photos hosted on their Pages. Since photos with no comments don’t appear in the Comment View, and they’re sorted by most recent activity, photo feedback moderation through the feature is much more efficient than through notifications or the standard view.

Users who come across the Comment View can also make use of it to quickly hop between conversations with friends on a big album of vacation photos they’ve just uploaded. However, there won’t be any flash prompts encouraging users to try it out, just a small title when the toggle switch is hovered over. The team told us “We didn’t want to go to crazy with introducing it since it used to exist. It’s the type of feature that if they really like, they’ll find it again.”
