The website is interesting. Lots of little hacks for things that range from useless to "I've never thought about this and it can actually improve things". A lot of stuff about locks and keys
I really like their simple point that some seconds are more valuable than others but that is in a different article.
I don't eternal utility with their ordering of keys, but I think it makes sense for a lot o them. And some people may never considered not having you their keys with the teeth all face in the same direction it just saves so much time and effort. I figure out how to hold one key and then I can just rotate till I get the one I need. I only have like five keys so I don't need any more organization
