The idea is this:

I build a platform that is as open as possible from the content perspective and allows you to organize your curators more nicely. This service will not necessarily require you to give posting permissions to streemian but only gives people a set of links they may (consider) to upvote that is curated by curie. The content can be very open to you but the underlying technology that does this for you needs to be closed source until I have another significant advantage over competitors.

Either way, I can understand that you'd rather prefer a open source solution and it is of course totally up to you. All I can offer is a probably quicker implementation as part of streemian instead of a new development from scratch ..
