You know how to use it, obviously. Also, all you have to do is look and see that people are constantly replying to the threads here to know that people still use this board.

I meant, it's been months since this section was used, there were two threads total at the time, and I have no clue what it's actually for.

What you do is you look for a well-written article on this page (for example, the Crock Pot) and then create a post on this thread. People will comment on here, either doing  Support Oppose or  Comment (written as Support, Oppose and Comment respectively in double-curly brackets), with reasoning behind their answer. If it gets enough support, an admin may make it the Featured Article.
