The sample gadget shown in this presentation [1], basically I think it
is this one [2], allows you to rate something (like it/dislike it).
It uses a key-value-pair to count the "likes", one pair to count the
"dislikes" and one pair for every user that voted
("[email protected]": "like").
So when a user hits "Like it", it takes the current "like count",
increments the value and submits the new "like count" and the user key
("[email protected]": "like").
And I think this could cause problems:
Imagine two users hit "Like it" at the same time. The current "like
count" is 4, so both users submit "5" as the new "like count". But by
doing so, one vote will be lost.
Wouldn't it better to just count the user keys?
