As you can see from the variety of answers, it is really a matter of personal preference. Some like chatting online, some hate it, and some think of it as a true waste of time.
In the end, the only thing about chatting online that really matters is if YOU enjoy it and derive benefits from it. In your lifetime, I suspect more and more people around the world will use online chatting. This means it will be available for you to explore in as much depth as you wish. And it will also be available for people to hate as much as they wish!!
So, do what makes you feel good and do not worry too much about what others think. The world is a big place and we are rarely alone in our desires.
