Very good point! It can be used for good in situations like the ones that you mentioned. We think it can be very good except in cases where it is used as a coping mechanism or it builds a psychological profile against individuals. One example being "How much personal information do you give out on platforms like facebook that you would not tell me face to face if I came up to you (random stranger) and asked? Don't take this the wrong way but "Do you have kids?" "What school do they go to?" "What time do you have to go pick them up? When are their birthdays? Do you drive? Have a picture of your car? How about family photos? Picture of your house in the background?" (All stuff that could normally be found on any facebook profile listed as public posts) We are not trying to slam social media (we use it ourselves)but rather bring some of the hidden dangers to light. I personally do agree with you on the bright side of it though. I myself have gotten intouch with some long lost friends of mine.
