Subtle changes, bugs and feedback

Also... TIL...

resp, err := http.Get(...)
if err != nil { return err }
defer resp.body.Close()
json.NewDecoder(resp.Body).Decode(&foo)

This leaves the HTTP connection open a fraction longer than desired, because it may not have consumed the input up to the EOF.

Need to add this after it:

io.Copy(ioutil.Discard, resp.Body)
