Tomo la posta del banner ut supra y detallo en inglés algo que siempre me hubiese gustado que tenga este buen amigo de blogger.
There's a lot of features that it would be great that blogger team deploy for the comunity, i have added some at Blogger Wishlist. I remember now the automatic integration with Analytics, the "most commented post" a widget about Creative Commons, and a long etc.
But most of all, and i think the most hard to apply, it's W3C Html Strict Validation to make able to reach w3c standard to all the blogger blogs. A good start will be to validate the templates provided by default.
