A lot of people don’t use favorites. I don’t, and out of the few random accounts i’ve looked at, none of them had any favorites either. Doesn’t invalidate the data but it does skew towards people who do have favorites. Another source of data is articles where people comment. You could also do ML to analyze whether the comments are positive or negative, guess the commenter’s age and demographic, etc. If someone comments on a particular topic, especially if it’s not as popular, it shows they’re interested in the topic. Maybe look at the writing styles and content of people interested in certain topics. Are people interested in X topic more likely to be negative? etc
