Me, too. Remember that old photos were taken blind, without knowing if the conditions were right or the pictures would come out until the film was developed. There is a lot of crap out there, and we have SO much documentation of so many things now. I'd save the really old ones - when photos were less common - and anything recognizably documenting people, technology, or interiors/exteriors of buildings still standing. If the photo of the back of your great-aunt's head is also the only one documenting the decorative details on the front porch, keep it.
Tagging is really, really important. Tag with every detail that might be relevant, and be consistent - provide a key to tagging terms for others to use.
Of course save the originals, and have the best photos professionally reprinted/restored as necessary so that originals are not on display.
