I still only have a baby so this isn't a huge concern for me yet, but I was reading this blog post and I thought it was interesting.

IDK, my house is not a showroom. I don't care if the toy room is messy. That's his space, his stuff and he can get crazy in there if he wants to.
I do ask him to pick up his toys before bath time each night. It takes less than five minutes.
I hate clutter. When everything else is orderly and put away when not in use the toys being strewn about are so much easier to handle. I sometimes have DS help me pick up throughout the day but generally as long as he's happy and occupied the toys can stay out.
To me toys on the floor that get cleaned up every day is not clutter. Clutter is when ever surface in your house is covered with stuff. Dishes, too many appliances, papers, mail, books, tchotchkes, etc.
I think I read this article like a year ago. I'm too lazy to go read it again now but I agree it's too extreme. My house always has toys lying around and hiding in places. DD "helps" me clean up but she's still learning. As PP pointed out, she mixes her toys too. I have cars in one container, Disney figures in another and veggie tales in another (etc.) and they all play together. Time to time I make sure they're back in their proper place but mostly IDC. I don't like tons of clutter and junk or excessive amounts of toys but despite the fact that I've only purchased a handful of toys we somehow have ended up with gobs. If they play with it and I have room for it, it can stay.
