At the risk of being Mr. Obvious, Postmates badly needs three things:<p>1. An Android app (I saw only the iOS app listed), with a direct download link, just for giggles.<p>2. A page on their website which replicates the app's functionality. I mean, it's HTML5/CSS/JS, right?<p>3. Smarter vendors, which accept and acknowledge orders by text, web, or (a different) app, to help the couriers earn, and to deliver the goods faster.
