You Don’t Need Every Customer ⇥ marco.org
Marco Arment:
Every app with a nontrivial number of downloads is likely to have comments, too, in the form of App Store reviews. This goes far beyond the app market these days, with stores like Amazon allowing anyone to review products and media, and sites such as Yelp that will publish anyone’s review of any restaurant, doctor, or church.
Consider, too, that people who have had a negative interaction are more likely to comment than people who have had an acceptable or positive interaction, making the product or service look worse than it potentially is.
