Discord isn't meant to be used side by side,it's default usecase is joining a channel and continuously talking while doing something else(mostly gaming).
not being able to snap the window seems to be a conscious choice on their part
I assure you there are lots of people who don't use it that way. It probably depends on what circle you end up in on it. There are text-based communities on there related to all sorts of topics. The Rust community was even considering using it as a default communication channel at one point I believe.
