To my mind FB groups have an almost worthless search function, compared to dedicated forums like this one. As a result, you see the same basic questions over and over - users never seem to search for answers and just ask the question again (and again and again).You only see those thing if you get involved or go looking for it
You don't have to do anything on Facebook only what interest you have, you visit the Zone, you can do the same thing to visit Syil on Facebook if you had to, you don't seem to put much thought into you posts
