Go Lang JSON & Topsy Twitter request

I built my first Go Lang program to request some data from the Topsy Otter API that queries Twitter.
It returns JSON and requests via HTTP
It doesn't unmarshall the JSON just yet...

package main

import (
    //"io"
    "io/ioutil"
    //"strings"
    //"log"
    "http"
    "json"
    "fmt"
    )

/*
{
   "request" : {
      "parameters" : {
         "url" : "http://twitter.com/barackobama"
      },
      "response_type" : "json",
      "resource" : "authorinfo",
      "url" : "http://otter.topsy.com/authorinfo.json?url=http%3A%2F%2Ftwitter.com%2Fbarackobama"
   },
   "response" : {
      "name" : "Barack Obama",
      "url" : "http://twitter.com/barackobama",
      "type" : "twitter",
      "nick" : "barackobama",
      "description" : "44th President of the United States",
      "topsy_author_url" : "http://topsy.com/twitter/barackobama",
      "influence_level" : "5"
   }
}
*/

type OtterResponse struct {
      name string
      Url string
      Type string
      Nick string
      Description string
      Topsy_author_url string
      Influence_level string
}

func main() {
    r, err := http.Get("http://otter.topsy.com/authorinfo.json?url=http://twitter.com/barackobama")
    var b []byte;
    if err == nil {
        b, err = ioutil.ReadAll(r.Body);
        r.Body.Close();
    }

    if err != nil {
        fmt.Println(err)
           fmt.Println("Whoa we really didn't make it!")
    } else {
        fmt.Println(string(b));
        var m OtterResponse
        err := json.Unmarshal(b, &m)
        if err != nil {
           fmt.Println("Whoa we didn't make it!")
           fmt.Println(err)
        } else {
           fmt.Println("Whoa we made it!")
           fmt.Println(m.name)
        }
    }
}
