not gonna lie, you don't need to be doing these projects. they're not really worth it. instead of building an app to help you meet up with your friends somewhere central just go meet up with them and explore together.
I don't need to be doing all of these projects, but I enjoy doing all of these projects, much more than I enjoy going somewhere to hang out with people. Not everyone is the same.
Eww, gross. Don't be rude.
Just to be clear, my comment about this being gross is about the rudeness of telling someone else their hobby is a waste of time, not about hanging out with friends.
