. >> it's always kpisd. it's one of the things that i think makes us human. but yeah, and obviously to know what is going on with your friends' live, not just your friends b people you care aut. people who you are interested and who aren't your friends or maybe on the riphery of your social circle. yeah, i think that those are all just core human needs. and until facebook there wasn't a great tool for doing that. but i think that a lot of that, in building that up was the last five years. i next the next five years is okay now are you connected to all these people, now you can have a better music listening experience, a better movie experience, you can see at your friends are reading and what news you should read first. all of these things i think are going to ge better. that's the thing i'm most excited about for the next five years. and if we do well i think five years from now people are really going to look back and say well, over the last five yes all these products have gotten better because i'm not doing this stuff alone, i'm doing it with my friends.
