I've searched the forums for this and it doesn't seem to have had anby serious discussion.
I think this site really needs an open web API to help the community thrive otherwise I think it'll die off eventually.
The 2 current phone apps (iOS and Android) have very low ratings and fail to work. If BC were to create an API for 3rd party developers to interact with the site similar to other sites like Goodreads and geocaching.com I think it will benefit us all.
It will generate a thriving community of developers creating numerous 3rd party phone apps, browser extensions, PC apps, web services, etc and extend the ecosystem for the better of the users AND the site founders! Bringing in people that wouldn't normally find the site or service. Making it easier to use the service.
This article on ZDNet makes the case succinctly: http://www.zdnet.com/---/opening-up-apis-brings-in-benefits
"When companies release their application programming interface (API) to third-party developers, they are also opening themselves up to benefits of revenue generation, user traffic and innovation, especially with the growing adoption of mobile devices among consumers today."
