There's a good reason for Facebook to keep Instagram going as a separate product, even if Facebook integrates some of its technology into its own service so that mobile photo sharing becomes easier. Google, for example, has kept YouTube separate even as it integrated some of its features into other products.
"Look at who Facebook is competing with — the Googles, Apples, Microsofts of the world. They have to build a strong brand and strong consumer platform," Gartner analyst Brian Blau said. "Having a separate social network ... is something they needed to do a long time ago."
