LinkedIn

I wonder what the lifetime of a LinkedIn group is? I doubt the company would disclose it, for it is the sort of detail that could affect its valuation. There are many groups on LinkedIn, and as a member of a few, I notice how the creator rapidly runs out of energy, or loses focus. The end result is that the group goes quiet, becoming the living dead. But what of the members of the group? Many appear to join because they wonder what they are missing out on; spongers rather than contributors, if you will. There's a low entry barrier to creating a LinkedIn group, which might be part of the problem, leading many to underestimate the effort and continuing persistence required.

There are probably many groups that are active and add real value to their membership. I just wonder what the ratio is.
