Until you do like step one of taking an appliance apart, and realize that the real manual is marked “for technician use only”, and it’s hidden inside of the appliance.
My washer and dryer both have good manuals complete with circuit diagrams under the top once i take a few screws out. My chest freezer has one taped up under the hatch where the compresser sits. My refrigerator has one hidden in the door hinge.
People usually don’t log stuff that they see every day. So a person who lives in Oregon (statistically more likely to be in doug-fir country) goes east and notices that a different tree predominates and they want to know what it is, they’ll log it.
Personally, I log stuff that I don’t normally see cause there’s a chance that it’s either: a rare native plant, a native plant on the edge of its range, or a non-native. Those are all things that I’m less likely to know off the top of my head, and I think it’s probably more important to tag for scientific purposes.
Ah, yeah, forgot that was another one I’ve done. It seems like I’ve taken apart most of my household appliances at this point.
