She has a point but its’ true about any online social sites. including this one. Much time is wasted and one has to be on top of their game to control how much time you do spend, for each person there is some relaxation. FB is very good to locate old friends and for this reason I would never ban it for myself. Because I located someone who told me about a software developer who could help me, I have been blessed with continuous employment for over 3 years.
The point she makes easily extends to newspapers, any advertising, or most news items in general.
Everyone is looking for some magic potion that will make all the problems disappear but FB is only a symtom, that is abuse of FB in terms of time spent, what one does etc.
