Design an experiment for a new feed feature on a network

Experiment designHard

Problem. The team built a feed feature that surfaces more of what your connections are doing (for example, highlighting a connection's new post or job change). You are asked to design the A/B test to decide whether to ship it. What is your design, and what is the main validity risk?

Before you reveal: say your answer out loud, as if you were in the real interview — get your reasoning across clearly first. There is no single correct answer: reading what the interviewer is really after and defending your own thinking is what makes an answer strong.
