The use of media for the social side of life has grown apace.

It is so easy to get into contact with friends and family across the world and to make new friends, who have the same interests, but it also enables unwanted contacts to pester us.

It can become a minefield, but it can have many good uses which we would do well to consider, be it in friendship, business, or with people who have the same legitimate interests and aspirations as ourselves.

It is to these that authors guide us and show us the best way to harness them. A useful guide.
