<span>{{item.name}}</span>
<span ng-show="show">{{item.thing}}</span>
</div>
</div>
</div>
//JS
function myCtrl($scope) {
$scope.editedItem = null;
$scope.items = [{
name: "item #1",
thing: "thing 1"
}, {
name: "item #2",
thing: "thing 2"
}, {
name: "item #3",
thing: "thing 3"
}];
$scope.show = false;
}
var editer = angular.module('editer', []);
//CSS
.wrap {
background: yellow;
}
.blue {
background: blue;
}

I made some small changes to your JS fiddle, and it works now. Basically, you only had one attribute called show for all items, but you needed to know for each one if it should be blue or not.
JS:
function myCtrl($scope){
$scope.editedItem = null;
$scope.items = [
{ name :"item #1", thing: "thing 1", selected: false},
{ name :"item #2", thing: "thing 2", selected: false},
{ name :"item #3", thing: "thing 3", selected: false}
];
function resetAllItems() {
for (i in $scope.items) {
$scope.items[i].selected = false;
}
}
$scope.selectItem = function(item) {
resetAllItems();
item.selected = true;
}
}
HTML
<div ng-app="editer" ng-controller="myCtrl" class="container">
<div ng-repeat="item in items">
<div class="wrap" ng-click="selectItem(item)" ng-class="{'blue': item.selected}">
<span>{{item.name}}</span>
<span ng-show="item.selected" >{{item.thing}}</span>
</div>
</div>
</div>

You can use a function instead and use the item show property.
HTML:
<div class="wrap" ng-click="toggleShow(item)" ng-class="{'blue':item.show}">
<span>{{item.name}}</span>
<span ng-show="item.show">{{item.thing}}</span>
</div>
JS:
$scope.items = [{
name: "item #1",
thing: "thing 1",
show: false
}, {
name: "item #2",
thing: "thing 2",
show: false
}, {
name: "item #3",
thing: "thing 3",
show: false
}];
$scope.toggleShow = function(item){
for(var i=0; i<$scope.items.length; ++i){
if($scope.items[i] === item){
$scope.items[i].show = false;
continue;
}
$scope.items[i].show = true;
}
}
