Crowdsourcing/Free content and open processes/Summing up
If the users of a resource are also expected to be contributors, then whatever makes things easier for the readers will indirectly benefit the resource by making it easier to contribute. For this reason, the hosting organisation needs to attend to the balance of power between it and the contributors. Restricting reuse of the content may well lead to there being no content, just as people are less likely to buy from a shop that has no money-back guarantee. Walls around content may keep some contributors in but they keep a larger number of potential contributors from improving it.
