I think you're definitely right that a non-arbitrary number of people fit that description, but I think most are likely similar to me in that I downloaded Instagram because my friends were on Instagram - If Facebook had created a photo sharing/editing app this good directly into their news feed, I kind of assume it would have been a hit. Who knows though...
