Pinterest is also rolling out a new sorting feature that gives you a way to sort by "Most Reactions" and "Most Comments," helping you quickly find the most popular (or unpopular) ideas. In the future, the new feature will even make it possible to sort by Pinner. The social network also promises to release a redesigned space for communicating with collaborators right on the group board. You can already start conversations in the activity tab, so we're guessing Pinterest is giving it an overhaul or introducing a completely new way to chat in the coming weeks.
