I’m reposting this list holus bolus from Peter Levine’s blog. It’s an excellent summary of what we can expect from volunteer networks, and very top of mind for me at the moment:
4) Volunteers may provide regular, written information under their own names and control, but few will contribute in a sustained way to collective writing projects. That problem can be overcome with scale but is serious in small networks.
5) Volunteers will generate wonderful ideas but are much less likely to implement them.
