Oh Google, you just get it. Plans for the Android Marketplace were revealed today, and it will be free and open to any developer. Like the App Store it will be a single portal for Android add-ons, but without the mystifying application and approval process. Developers simply need to register, upload the app and write a description; users will be able to rate apps and give feedback YouTube style. The Market will be available in Beta form on the Dream and initially support only free apps, but as it moves to final there will be both paid and free content.
