Why isn't academia a more social activity?
Think of this analogy.
You are interested in say a subset of research on morel mushrooms.
You know who the reputed people who publish are so you "follow" them and their profile. They did a new peer review of a newcomer and you get alerted. You check their work and are impressed so you follow them too.
Your favourite researcher Also curates "his" favorite researches and researchers on their blog so you are one click away from their opinions on what is good or bad.
Compare that with a "reputed journal". The way the system is designed, the journals work of sorting and filtering, the reader is expected to trust their research of choosing the work so you trust their judgment and you auto assume the work is good.
Why don't you democratize that work to domain experts itself and everyone helps everyone else. Isn't that the case with everything online?
