Remember categories? They were really controversial when they were first introduced, but now they are invaluable, and it's hard to remember what MediaWiki was like without them.

I have been wondering about this, actually. (I'm newish to WP). Could somebody show me how exactly categories are helpful? A link would be fine. It's hard for me to see the usefulness. A link or three would be fine, maybe an old pertinent discussion. Thanks.
