How do you engage with hundreds of people as “friends”?
On a personal level, you may engage deeply with a few, maybe a few dozen, electronically, there may be a group with a specific interest, and you engage with them in a club-type situation, 100 perhaps,150?, but any more and it is not engagement, just some sort of casual interaction, in no way engagement.
The depth of personal relationships simply do not scale.
Our social networking tools have opened new avenues of connection, they are wide, but the width is not a substitute for the depth that can only evolve through a personal connection.
This is one situation where numbers simply do not count, where less is often more, so do not confuse the numbers of contacts with quality of interaction.
