While you can't see the Added date in a column, you can sort by it and group by it. For me, that covers about 95% of the cases -- usually I either need to know where it was added relative to a bunch of other things (group or sort to the rescue) or occasionally I want to know exactly when, but then usually only for one or two items, so the inspector is fine. Column views only show you the date, not the time.
