I know we discussed this on HipChat, but please follow the [jQuery Core style guidelines](http://docs.jquery.com/JQuery_Core_Style_Guidelines) for the future. Eg. whitespace:

if ( state.suggested ) {

instead of

if(state.suggested){

It would also be good if we're consistent with the usage of `jQuery` or `$` -- it seems that `jQuery` is dominant here.
