Personally I like to see how others store or display their collections. It gives me ideas and it is also a way of discovering display accessories that a person may not have known about (such as Flex Display stands that a few people were interested in).

As for large army's of same figs, I agree with you for the most part. It is cool to see but personally 3 or 4 of the same trooper is enough for me. But everyone is different and has different priorities so if they have the time and money to put together large army's then more power to them.
