Benedict Evans:
Just as Yahoo’s hierarchical directory didn’t really scale after 1996 or so, so too app stores have not scaled as a discovery platform. Further, though there are lots of ways that the execution of the app stores could be improved, this still ultimately boils down to saying ‘Yahoo’s home page should be better’ back in 1996. Indeed it should have been, but the answer was still PageRank. And we have no analogue of PageRank for mobile apps.
