Did you even read the article, or did you just come here to toot your own horn? All of your "advice" is exactly addressed by Fluent, e.g. built on top of Gmail, better search, better inbox navigation, and better attachment handling.
I have no idea how successful Fluent will be at all those things, but it's just peculiar when a site says "we're tackling problems x, y, and z" and you come along and say, "your ideas suck, try addressing problems x, y, and z instead."
