As a new PM for Facebook, how would you help in improving FB's meaningful social interactions?

This problem falls under the category on how to improve a product feature or overall product in question. 

Step 1 : 

-Clarify "Social Interaction" and what would make it "meaningful"

 -Does high Engagement /Like/Share/ Comment   answer 50% of this qurestion to have a       higher social interaction

 - Depending upon World Affair "Meaningful" can be different things ; It would be helpful        to   understand the North Star Goal metric for this improvement

- If we want to reverse engineer and assign a tag to "Meaningful" we can analyze that

Foe example an updated question could be "How can improve and have a more meaningful engagement on FB around LGBTQ+ rights or Supreme Court Nominee in US "

We can assign meaning and then design a Analysis around it to track Engagement. 

Step 2 Prioritize  and propose a plan to track the metric around it (lets Assume we track this metric for 30-60-90 day period)

Lets assume our new problem statement is "How can improve and have a more meaningful engagement on FB around LGBTQ+ rights or Supreme Court Nominee in US "

  My first Metric to track would be : 

-Frequency and Quality of Engagement aroudn posts / like /comments /shares around posts related to these topics 

- To be meaningful it has to be with real people ; identify SPAM or BOT Account and remove them 

-Check and Validate Engagement on FB User Group Activity 

-Check and track the DAU, # Avg Time spent on app /user /post for these topics

Step 3 Success Metric: 

--> If we see organic growth in Enagegement related to the topics under scanner and natural enagegement (Quality and Frequeny) 

--> SPAM /post and BOT/post is minimum

--> DAU/MAU for the period wer track this meaniful interaction over a tops shows the stickiness of the interaction and engagement level on App
