While it's a bit much to say that Instagram is ruining vacations, it's also a touch naive to say that the product is facilitating "memories and being able to share our awesome travel experiences with friends and family is". Social media is, for the most parts, a tool to elevate your perceived social status. So saying "It isn't ruining vacations, its redefining them" in the context of Instagram just reads like a Zuckerberg pull-quote.
