"Less is more... especially in your first few iterations."
I can see how this would lead to 'holes' in a platform or generally ambiguous application boundaries.
right...that's a valid concern. i think however, when weighing the options between releasing something that's fully robust and polished (say 12 months time) versus a minimum viable product (say 3 months time) most would lean towards the latter.
there is just too much rapid iteration that can (and probably) will occur after releasing the minimum viable product. if you wait too long, you'll be behind in the race.
