Jarvis, good start, but it's probably best to create a new variable for the result of the cast, and you need to finish the if... else... Note that the second return statement replaces the return 0:

  public int compareTo(Object obj) {
    BlogPost other = (BlogPost) obj;
    if (equals(other)) {
      return 0;
    } else {
      return mCreationDate.compareTo(other.mCreationDate);
    }
  }
