Since we started the #longreads hashtag in 2009 to share great reads on Twitter, curation has been the beating heart of Longreads. All year long, we highlight our favorite stories in the weekly Longreads Top 5. At the end of the year, we reflect on and share the pieces that stayed with us, a tradition we’ve kept for 10 years. This year, we’re highlighting the best in personal and reported essays, investigative reporting, features, and profiles — and also including two new lists of recommendations and favorites from our readers.
