There's definitely stuff I don't throw out when that would be the easiest path because I feel bad about it going to the dump. A dead treadmill with a working industrial motor that I'm trying to find someone who can use the motor. The kids' old swing set with perfectly usable pressure treated pine. All manner of electronic detritus (anyone need a 25 foot VGA cable? How about a 35 foot HDMI cable that's not current spec? Old component cables? An old Dell minitower? Wall wart transformers? ...). Etc.
