Well, I guess I shouldn't judge — you never know about these things. But an article on Mobile Crunch makes a fairly good case that a successful PR firm is faking app reviews as a way of promoting their clients' apps. The company denies it. But it does seem undeniable that some of the reviews for new apps are planted. I realized when reading this article that when I look at app reviews, I always subconsciously dismiss certain ones that sound phony. There's just something about them that doesn't sound genuine. And usually a surfeit of exclamation marks. Plus, they appear so quickly after the app is released. This article, if true, corroborates that intuition. Usually, though, once an app reaches a certain threshold of reviews, it's easy to get a sense for the merits and weaknesses of the app. The system seems to work well overall. You just skip over the fakes.
