Google has had this sort of functionality for around five years, which makes Apple's reluctance to add it all the more curious. Anyhow, next time an app isn't working exactly as advertised on iOS or OSX, if you leave a comment about it in the App Store there's a chance you'll hear from the developer. If you're a fan of trolling though, that snarky comment might come back to bite you.

Once you submit a review, should a developer respond, you'll get an email that offers a chance to update your original review or contact the developer directly. On the developer side, Apple's outlined how app-makers should use the feature, too. Basically, respond swiftly and follow Wheaton's Law. And really, that's it. Maybe this two-way communication will result in developers being more communicative and result in faster updates.
