After my last post, I came across some discussion about implementing JSON Feed, and whether using a template is a good way to implement JSON Feed in a site. The concensus seems to be “No,” with one of the authors of the spec weighing in. For the most part, I do agree – a template is more likely to break under some edge case than a proper serializer – but until there is more support for the spec I see it as a pragmattic short-term solution. So proceed at your own risk for now!
