In prosperous, secure societies, most people do indeed have plenty of free time. Some use it to tell their friends what they ate/who they dated/what they are listening to/where they are at/the political assassination they just witnessed. Others may use it to talk drums on a specialty discussion board. Whether that is a waste of time is entirely up to the person taking the time.
