As we strive to show fresh, popular and relevant content to our users, one of the problems we faced when developing Stack Decisions was to show a feed with more than one activity type. We show Decisions, News Articles, and Stories on our feed and composing them in a single feed proved to be a challenge.

We solved this problem using Stream's personalization feature to build a scalable activity feed. As the parameters that determine popularity vary for different activity types, Stream helped us normalize the popularity scores and aggregate the feed.
