Superusers don’t work for free, and neither do people who operate as hubs in a network.
The thing is, no-one is solely a hub. My network is part of other people’s; my network is a small part of a much larger system. That means you might be a node or a hub and there’s an art recognising which you are in which context. When you realise you’re perceived as a hub by others, make sure you take time to appreciate the benefits.
As Harold Jarche says:
Networked individuals are the new engaged citizens.
