Linux is an open source operating system based on UNIX. There are multiple different distributions (different versions developed by different people) which offer varying benefits. All distributions offer much more customization than windows, and some distributions have a similar GUI (graphical user interface) to windows, making the user experience very similar.
One of the biggest advantages to Linux is that Windows tracks user data, so users who care about privacy usually choose Linux.
Everyone who would care about Reddit in the fediverse left Reddit already
I immediately thought about connecting multiple of these together to make a train haha
