Mark Zuckerberg: “You can’t 80/20 everything”

We had to do some manual work for every school that we released. Facebook ad. And I remember having this debate where Dustin was like, it would be easier to launch new schools if we didn't have to have course catalogs for each school. And we just had this really long debate about what quality meant for us and the community that we wanted to establish. In retrospect, you know, maybe it wouldn't have had a huge difference on how things played out, but it definitely kind of set this tone where there's a lot of kind of clean data on Facebook. You can rely on it. It feels like a college specific thing, which was valuable early on for setting the culture, even though obviously since then we've grown beyond that. There's the famous 8020 rule where you get 80% of the benefit by doing 20% of the work, but you can't just 80, 20 everything. There have to be certain things that you just are the best at and that you go way further than anyone else at to establish this kind of quality bar and have your product be the best thing that's out there. So whether we had to do that one or had to do something we had to do, I think enough of those things or else we just wouldn't have been the best service out there.
