The change of rules is inspired by the critical feedback from (part of) the community. Addressing their issues by changing the system could means that this could build up greater loyalty amongst the community through this responsiveness.
Accountability
It is one thing to tap into the power of the distributed flexible volunteer ethic, but corresponding systems of recognition and accountability must be in place. This could be such as system, according to my opinion.
Chance of game play
Game play is not necessarily a negative development. The outcomes can possibly enrich the community and the platform even further. It is unavoidable that through time the demands of the users will change and the system needs to be adaptable to that.
“The interaction of people with information systems is recurrently marked by play and experimentation, as people test the limits of their settings and manage the consequences of unexpected interactions and altered contexts. Digital social structures disrupt the boundaries that define social communities, but the reassessment of context and performance that accompanies this is endlessly generative.”
There will always be a part of the community that will test the boundaries of what is given and explore possibilities. Because the outcome of this is unpredictable, it could also proof to be beneficiary to the community.
