Nice example of a small change both at the interaction and UI levels. if you have longish Amazon wish lists, then it might be that you add an item more than once, for instance because you forget that it was already here. I remember that back in the past, in this case the system told you that the item was there indeed, but you had perhaps to browse through several pages to actually find it. Well it seems that the designers at Amazon took good notice. Now they put your recent, duplicated add at the top. It’s smart also a proactive move that doesn’t come out of the blue, but as a calibrated reaction to an explicite action on your side. So, in my opinion really much an interesting example of something like an interaction style. Then, given how widespread lists are in today’s social InterWeb (interwebs?), it would be nice to see others follow here…
