BB was quite agressive in setting deadlines for submitting apps (port-a-thons, $10000 pledge, dev alpha exchange...) that most developers submitted their half-baked app quickly, just to get in there. BB went for numbers, rather than quality, for their launch. Once the dust settles, I'd expect a lot of these apps to be updated to become more useful, or to go down in rating hell, forgotten in the store's abyss like most of the Android/iPhone apps.
But right now, their app world is a bit lacking...
