-Takes an `io.Writer` and an slice of `interface{}`.  Note, if you have a
-type safe array of your structs, like,
-
-```go
-var blogs []*Blog
-```
-
-you will need to iterate over the slice of `Blog` pointers and append
-them to an interface array, like,
-
-```go
-blogInterface := make([]interface{}, len(blogs))
-
-for i, blog := range blogs {
-  blogInterface[i] = blog
-}
-```
-
-Alternatively, you can insert your `Blog`s into a slice of `interface{}`
-the first time.  For example when you fetch the `Blog`s from the db
-`append` them to an `[]interface{}` rather than a `[]*Blog`.  So your
-method signature to reach into your data store may look something like
-this,
-
-```go
-func FetchBlogs() ([]interface{}, error)
-```
-
-##### Handler Example Code
-
-```go
-func ListBlogs(w http.ResponseWriter, r *http.Request) {
-	// ...fetch your blogs, filter, offset, limit, etc...
-
-  // but, for now
-	blogs := testBlogsForList()
-
-	w.Header().Set("Content-Type", jsonapi.MediaType)
