TLDR: this post is entirely to calm advertisers, it can be boiled down to "don't worry, we still prioritize brand safety like before".<p>It does have this gem in it:<p>"What has changed, however, is our approach to experimentation. As you’ve seen over the past several weeks, Twitter is embracing public testing. We believe that this open and transparent approach to innovation is healthy, as it enables us to move faster and gather user feedback in real-time. We believe that a service of this importance will benefit from feedback at scale, and that there is value in being open about our experiments and what we are learning. We do all of this work with one goal in mind: to improve Twitter for our customers, partners, and the people who use it across the world."<p>What a weird thing to say... A/B tests are a thing, does anyone buy that experimenting with new things by rolling out new features to all users at once is a good strategy?
