Most special operations forces are "regionally" <span>oriented.
This helps those forces to enact better functionality as these personnel already have all the information and acquaintance for the region in which they are appointed. Cultural awareness and language capabilities come handy while pursuing a case in the specific area.</span>
Since I don't know what "these" refers to here, I will just assume that the question addresses social networks generally.
Some impacts are:
Positive
-better information
-security (you can mark people safe during Earthquake)
-faster contact with peopl
-possibility of forming groups
-additional communication platform
Negative:
-less privacy
-lack of control over data
-being able to spy on people
-being able to find things from the past
-bosses spying on their workers
