close apps frozen in multitasking?

[glen e]

I know they are not running, but is there any reason to close them from the multitasking bar? At the end of the days seems like I have scads of them "open"...

I'm constantly clearing the multi-task bar...just a "tick" of mine I guess. But it shouldn't eat up resources or anything as it "freezes" the state of the app when not in use. When you open it again, it'll be in the same state as when u closed it.
