Talk:Wiki instructions

Is it worth laying out a basic category structure and asking users to adhere to that? And perhaps pointing them to the special page for categories so they can see what already exists and try to include relevant information in pre-existing categories?

If the wiki grows the current state where there are 3 or 4 categories for steam, a dozen different fab categories etc etc, is only going to get worse and make rectifying the problem that much more difficult.
