I like the idea but sadly I'm sure it's more of a marketing effort than an actual platform. I've been saddened to not be able to find social media marketplaces that provide an actual twitter platform (ie programmable). All you can buy is x thousands of account blasting an identical message. Or maybe I haven't been looking hard enough?
