Both . I typically use fb to for college purposes as most students created groups for individual classes which offer a lot of content like exams , homework and so on . It also helps me to get in touch with someone if you don ' t have someones number . Most of my friends college friends i met through a facebook message instead call sms . Instagram is for the individual style you follow be it music , fashion or so on . It also helps me to get know what other people like . For example you meet a new girl and talk to her and you are going to see eachothet again but you have no clue what she is into you can just check her instagram and you will get a lot of information . For example if she likes fitness , travel , certain music , etc . it also works the other way around . Keep your profiles clean and don ' t post unnecessary content . I feel like most first impression are now made virtual instead in real real life .
