 network effects. So this is the thing where a product becomes more valuable the more people have it, right? There's a lot of big platforms that have big network effects that work very well. If you look at our app, storage doesn't have network effects, file browsing doesn't have network effects, offline sharing does have network effects. Offline sharing is really only useful if everybody around you also uses the same technology to do offline sharing. There's about five different technologies out there to do offline sharing. So this is a pretty difficult market. What you see, very interesting with offline sharing is that it's extremely local. You have some cities where people use technology A and some cities where people use technology B. And that is kind of very clearly network effects in action because if I'm in a technology A city and I think technology B is better, I need to convince everybody around me that B is better before it actually starts working for me. So I think network effects can be very much of your advantage if you're one of the first to build the network. It can be very difficult if you're coming into a place where there already are quite established network effects.
