This, and all subsequent store callbacks, should be redefined
```javascript
function(err, whatever) {
  if (err) return utOh();
}
```

And yes that'll probably get repetitive and should be a wrapper, maybe:
```javascript
function respondErrors(response, callback) { // rename to taste
  return function(err, whatever) {
    if (err) return response.render(/* some error template, oh probably also set status code 500*/);
    callback(whatever); // there are extensions for arities other than 1 without hardcoding for arity
  };
}

// then eventually
store.frobnicate(stuff, function(hazStuff) {
  yay(hazStuff);
});
```
