Como administrar blogs de blogger con Google Apps Script

Llevo años haciendo blogs como afición ( ojala fuera como profesión, pero no, no da dinero para eso :) ) y uno de los problemas que siempre he tenido es el de ir mirando las visitas de los blogs uno a uno para llevar el control del tráfico. Si tienes dos blogs no es un problema pero si tienes 20 ( o más ) puede ser realmente tedioso.

Es por ello que he montado un script que se conecta a la API de Blogger saca la información de tus blogs y te dice cuantas visitas has tenido en cada uno de ellos. El resultado lo da en forma de web, de este estilo:

Es un script relativamente sencillo y al que le podéis sacar mucho partido, pero si no tenéis experiencia en GAS os recomiendo que primero os miréis este link: http://googleappscriptsweb.blogspot.com.es/2015/03/como-crear-una-web-dinamica-con-google.html

Os dejo el código:
