Re: Is there an optimum level of apps?
Indeed - to some degree, an application download site needs a sufficient number of applications for people to regularly check it, but beyond that, for a developer less competition is better, and the issue is "installed user base" versus "number of applications".
I get 100 times the number of downloads on Nokia Store (with Symbian) than with Android (for various different apps). And as a user, the greater number of apps on Android just means more apps that basically do the same thing that I have to wade through (and far more that are ad-ware).
Though I think the article is misleading - the blog says that the deadline for the $10,000 revenue thing, but I see nothing about an extension for the $100-per-app port-a-thon(?), the last of which just took place. Still, great that it looks easy to port (apparently easy to repackage Android, as well as supporting the cross-platform Qt).
