Marco (or rather Instapaper) is not the garden variety app. I have noticed that many apps, especially games, launch as free in order to garner reviews, and then switch to paid later. Some sites (eg. AppAdvice) will not promote free apps unless they have at least three stars, so I can see why the developers feel the need to beg for a rating. That said, the chances that I will stop in the middle of doing something to exit the app in order to rate it are pretty low. Conversely, there have been occasions when, having finished with a game, I have looked for a "rate this app" button and couldn't find it. Unless the app/game is exceptional, I may not take the time to go to the App store, search for the App, yada yada, in order to rate it. I suggest every app should have a "Rate this App" on its main menu. Even better, I wish there was an API that would allow developers to ask me to rate an app in-app, without having to start up the App-Store.
