As we did last year, we’ve asked a couple of dozen people from all around the news-nerd community to tell us about one thing—article, feature, app, tool, or something else entirely—that they loved in 2015. This week, we’re publishing their responses, from interactives to project management software. We hope you find here at least one thing that eases your work, inspires new angles on your stories, and helps carry you through to 2016.

Latoya Peterson creates all kinds of groundbreaking digital work with Fusion. We spoke with Peterson about her Mental Map project, an interactive series that traces and celebrates creative roots.
