Forums getting older but they are best way for communication. In past we use IRC but forums are best.
Forums are not dead, I have some that are still very active. They may seem to be dying because of the simplicity to set one up and everyone under the sun is trying to start one. They think it will be easy and get discouraged after a month when they are having conversations with themselves.
How come forum will be dead. Since a lots of people are looking for an answer to their query. And for me forum is the best way to find your answer. So, it will not happen that case.
