Halide Mark II
Usually a v2 of an app or product comes with some new features and a surprise or two. The Halide team, however, created a 10-part newsletter to demonstrate how to use the app. I love when a team dedicates resources to education and fun. Most teams would settle for in-app screens or perhaps a video. A newsletter that finishes with a shareable artifact is clever and innovative.
I recommend reading the Halide team’s incredibly thorough blog post about Halide Mark II as well.
