I've constructed an iPhone-app where the users can "friend" each other and it works fine.
The reason that I started this thread is to discuss whenever its a better/more modern approach to let users follow each other instead (Instagram, Twitter) rather the "traditional" way (Facebook before the possibility of following people).
Are there any advantages of using the "following" model?
Why and when to go with the "friend" model?
Of course it has a lot to do with what kind of community the structure should be inside, but for my project that's about exercising and workouts i think that I might have to toss the "friend" model and go with the following-method. In my case, people might want to show their workouts to people that they don't even know.
What do you all think?
