Introduction to User Reputation and Recommendations

Welcome to one of the most exciting lessons in this course, Reputation and Recommendation. You might be wondering — aren’t these two totally different things? Why are we talking about them together? Well, not really. Let me explain. Both reputation and recommendation systems are built on one core thing: user interaction. Whenever a user does something on your platform—whether it’s viewing a question, posting an answer, or upvoting—that action tells you something. Either you reward it with points (reputation), or you log it to learn what the user likes (recommendations). For example, If a user checks out a question detail page, that probably means they’re interested in that topic.
