I think "the reason thing" changing pictures all the time is an inconvenient/annoying distraction. Cool effect but it doesn't help to explain your service at all (neither sells it). Besides I don't need a zillion random reasons, I need ONE good reason to use the product. To find this one good reason, you need to put a lot of effort thinking and iterating, maybe with the aid of A/B Test. But I like the concept and the product, congrats for your launch.
