I agree with Zombie and BlackWidow. I can't stand the cutesy things--though I've recently come to the conclusion that something is better than nothing, or more accurately, that if my neighbors want to put out a cutesy blow-up ghost in their front yard, it's better than if they'd done nothing at all. Not in my house, though!
I don't usually do the little knick-knack things, unless they're skeleton-related. I have a couple of those I keep out year-round, so I don't bother putting them away around Halloween (when it's actually appropriate for them to be there!). However, even those are gifts I've gotten from other people, not things I've gone out and purchased myself. So I wouldn't be in the market for them, if that helps at all.
Curiously, I really love seeing them in stores, though...
