Maybe there's no need. Or maybe the real problem isn't app discovery - but a problem of managing more than 20 apps on a phone and remembering to use them in the right context.
It might be a personal preference but "browsing" apps in the store isn't something I do at all. Most installs come from directed searches after reading reviews online, buying new Hardware (e.g. pulsemeter) or subscribing to a new service (e.g. spotify and friends).
EDIT: Simply being available in a store is definitely not enough to be found. Get a good webpage show the benefit (most apps are struggeling here ;) ) and give me a chance to try it out without much hassle
I'm actually currently working on such a setup.

You mean, like the "internet"?
Inside their Mall, different third party stores could focus on different niches and demographics with totally different criteria for including and rating apps with different UX to browse and discover products. Some could use expert reviews, some user reviews, others taste based recommedations. Its crazy to think there could ever be a "one size fits all" store for all types of people and all types of activity that digital devices are used for. Maybe an IGN store, a LifeHacker store, a ThinkGeek store, a Fortune store etc.
Apple/Google/MS could spend their time on the simpler effort of curating and promoting good stores instead of good apps and offer them a typical referral fee on each purchase. I think everyone would benefit - better shopping experience for users, better niche surfacing for developers, new revenue source for tech reviewers, simpler curation job for the platforms.
