We just have this playbook for how we do this and there's like phase one is build a thing that kind of sparks some joy and that people appreciate then from there you want to get to something that is retentive so that way people who have a good experience with the thing come back and want to keep using it and those two things are not they're not always the same a lot of there are a lot of things that people think are awesome but may not you know always come back to I mean some of what people are seeing now around like chat gpt is part of that this level of ai is it's like a miracle right it's awesome but I mean that doesn't mean that everyone is gonna have a use case every week right so so I think that there's first is like create the spark second is create the retention then once you have retention then you can start encouraging more people to join but if there if people aren't going to be retained by it why would you ask people to go sign up for something right so kind of step one spark step two retention step three growth and scaling the community and then only at that point is step four which is monetization we take a while to go through all those I mean we're really in some sense only getting started on the monetization of the messaging experiences like whatsapp now with stuff like business messaging but took a while two billion people use the product every day right so it's I mean we like we scaled it pretty far but I think with our model that that sort of works so
