Many system design problems have feeds or timelines:

Common Concerns

  1. How feeds will be generated from available contents/posts
    1. Chronical order of Followed
    2. Custom Ranking
    3. Recommended Posts for new users / less follow
  2. Pre-computation of feeds
  3. Celebrity problem
    1. Hybrid fan-out
      • Celebrity vs Non-celebrity
