I understand why open source aligns well with Curie's spirit and that has always been the intention. However, personally, I feel Curie's primary goal is to curate posts; reward and retain new authors. So far, we haven't really heard back from any developer who would make this an open source project and finish in a timely manner. So it's a simple dilemma - consider closed source by committed developers or the new authors you seek to reward suffer due to lower operational capacity.

Of course it's important that even if it's closed source, other curation guilds have access to this functionality.
