I believe so.
(1) The grammar and structure of sentences may tell me whether someone is educated or not.
(2) Those who post many questions one after the other, yet know the answer, tells me they are looking for attention or are trying to manipulate the HP system to get more traffic.
(3) Those who post many pictures of themselves tell me they are either insecure or self-absorbed.
(4) Those who express concern over their mentality over and over tells me they are crying out for help.
(5) Those who casually ask questions about our day tells me they are looking for socialization and just have a need to express themselves.
(6) Those who ask questions about current issues may be looking to see how society reacts to gather what the majority is (this is usually me... haha).
