I think this is a cool idea, and the blog post made sense. This is a really nice way of making visualisations reusable.

Judging by how others have missed the point though, you might want to work on simplifying the pitch. How about starting the post with a simple diagram explaining the flow like:

(code your visualisation) -> (add the BlockSpring API) -> (we generate a web interface for your visualisation) -> (now anyone can use their data with your visualisation)
