So, I found something very interesting in Mark Zuckerberg's post about acquiring Instagram:<p>> we're committed to building and growing Instagram independently. Millions of people around the world love the Instagram app and the brand associated with it, and our goal is to help spread this app and brand to even more people.<p>Facebook has always integrated whatever it purchased (that I know of) very tightly into the core product, or just done an acqui-hire. Instead, they've taken what is arguably the best way to share photos and decided to keep it as a product that exists on its own.<p>This is a major strategy change for Facebook and speaks to something I have suspected for some time - they now understand that in order to continue spurring growth, they cannot just acquire and roll in every product. As the ecosystem starts to hit a long-term maturity cycle, other products that fulfill particular functions better will be key to maintaining dominance over the market as a whole.<p>Let's face it: G+ cannot topple Facebook (though it probably wasn't intended to anyway), Twitter is fairly specialized and Pinterest has come up with a new way to share that fits neatly with the other two. Instagram makes immense logic as a purchase for Facebook as they'll control one of the most important ways people share photos outside their product, neatly roping everyone that uses it right into the FB circle without feeling forced to do so.
