While I agree to a certain extent, the core networking effect of FB is slowly but steadily dying.
- The average time spent per person is getting less and less.
- The number of original posts is shrinking, people simply repaste links from other places.
- It's becoming a farm for advertising agencies and is losing user appeals.
- The younger people are moving away from FB coz their parents are on it too and thus it's not as "cool" as some of the other new apps like snapchat.
