Nope. Unless you are a psychopath you have always managed friends/family even if was managed informally in your head. You used to have a Rolodex of phone numbers and addresses. You may have even kept additional information about the person in your Rolodex, perhaps their birthday or anniversary. Important dates and social obligations used to be written on a wall or desk calendar so you didn't forget. You make notes (written or mental) of people's needs and preferences in order to accommodate them. (ie "I better have a vegetarian meal for Susan.", "John works nights so I better not call him until 6." "Sarah likes red wine.", "Joe doesn't like clubing.") You store in your mind what is happening in friend's lives to talk to them about it next time you see them. You made a paper list of people to send out event invitations, thank you notes, or Christmas cards so you don't forget anyone.

It's all social management, even if informal. But it's so natural you might not have thought about it as "management."

Nothing wrong with formalizing it and taking it all digital, if anything it can foster closer relationships if it's easy to use and consolidated. Someone can only remember so much at once and its great they care enough to store that information for easy retrieval in the future. We have never, as a society, faulted people for writing things down, (Rolodex is a generic trademark, for crying out loud), we are all only human. We don't think twice about setting a reminder to take medication or water the plants.
