I found this article about iPhone apps interesting, especially from an MMO fans perspective, as I believe the study is a good reflection of society as a whole right now. In short, lots of initial interest followed by near immediate decline, in this case 50% or so. Sound like a recent trend we are familiar with?
Granted it’s not a straight up apples to apples comparison, as the app store has a bunch of unique factors associated with it, but I think there are some correlations. The trend of ‘new shiny’ applies, as people jump on what looks interesting with limited knowledge of the product. Instead of long magazine previews and reviews, you have a short developer description and user reviews that at times resemble the WoW general forum in usefulness. You more or less sell an app based on its icon and a single screen shot, which makes it very difficult to sift through the clutter and find the few solid apps. Sounds a bit like the F2P MMO market, does it not?
