I am both a FB user and a FB septic (which is not coherent).
Irrespective of what I think there are getting more present online, smarter, smartly intrusive....
You could even argue that FB is a resilient business model as a user that loses his job is more likely to spend time on it..
I am not a specialist and probably underestimate the potential but i respect price projection potential and here it is high.
Anyway: as long as above 77, it could be very bull.
