alt Hacker NewsApp tells customer to review it. Customer reviews the app honestly (the nag is annoying and deserves 1 star). Seems like the nag screen worked? :)
(Although in seriousness, I get this point they make further down in the article: "If we don’t request ratings from all users, then the self-initiated ratings tend to be disproportionately people with a complaint rather than satisfied users. ". That's a real problem. )
There are ways to non-annoyingly ask for a review.
Wait until the user has meaningfully used the app. Don't interrupt the user mid-flow (a banner on the dashboard, a call-to-action on a piece of existing copy) with a modal. Provide a clear "never ask me" option.
