@Sascha That's well said! One of the items on our roadmap is a "mood board" mode which will allow users to arrange pins in a 2D layout. The person who suggested it was thinking about helping designers do their work, but in fact, everyone needs to "design" things here and there, and having a visual tool to connect different pins/ideas spatially can help communicate thoughts and concepts in totally different ways.
It's also important, however, not to get carried away thinking that a purely technical solution is going to make the world better on its own, as that's rarely the case in reality. So many developers get hyped about a new idea for an app that will make money AND save the world and then the whole "saving the world" thing gets stuck in the mud when they realize that they have to put food on the table. Most often, what makes change in the world is change in communities, and that starts with relationships of mutual support and friendship between people like you and me. It's learning how to make the necessary changes in our own lives and changes in society at large at the same time that's the real challenge, and it's one that we're trying to carry forward even as we develop an app.
