Before the social media era, how people communicated for hobbies, relationships and stuff. And, how different cultures used to interact when there was no social media. The answer is clear forums, used to rule that era. At forums, you can most certainly find people or a person that matches you with a funny picture and a strange username. However, even with the presence of the social media, forums are not yet extinct and in fact they are quite popular among the communities who  seek to learn language. There are several Chinese forums which you can browse through and these are:
Subreddit Chinese forum
