Some of your younger friends / relatives / colleagues think Facebook is for their parents’ generation and put the stuff they want their contemporaries to see on Instagram. But not too young, there’s a generation behind them that thinks Instagram is for old people.

In terms of pure functionality there’s absolutely nothing special about Instagram. At this point the two products are reskins of the same functionality.

Facebook is a lot more comprehensive, I think. But I've also deleted my FB account a while ago.
