This is not good it's been used for the vast majority.

Companies and big communities use it as a forum, sharing knowledge more or less important.

For example, i dabble in modding games, nowadays i need to join a game discord server and ask there hoping that someone is kind enough to repeat for the nth time something asked already, probably several time a week.

Most often than not, you don't get an answer due to several factors, one of which is that if you ask when the people that can help are not online, nobody answer really.

On a forum you could have searched your question and find some answer anyway.

THAT is a very big problem. Knowledge is walled in and the search provided is the equivalent of digging in the sand with a spoon.
