Finding connected people to help develop your community sounds like a strategy that should work. It doesn’t.
These connectors are too busy. They have their own audience. They usually don’t want to help. They’re happy doing whatever it is that made them connected. Sometimes this is their blog, sometimes it’s a different audience.
The people you want to target are the ones that are most passionate about the concept. You want the most dedicated. You usually want people that have never properly participated in an online community before.
Go for the passionate fresh-faces, not the relationship-weary connectors.
