I do this with my little brother (8th grade) all the time, his perspectives on the unique lives of middle schoolers (which are definitely unique in this day and age) give the technology this whole new life.

Also the thing with Instagram following ratios is frightening. My brother talks all the time about following and then unfollowing people to trick them into follow you, it's all an unnecessary popularity game (I guess I was never one to understand popular people though).
