So if you want to poll a service periodically, you can do that ... or if you want to use a websocket and just leave a pipe open to refresh your client-side model ... you can do that too? Got it. Thanks.
Yep. The $http service in angular core basically does your standard Http stuff (with some nifty additions like caching and promises), but people have built services to do sockets, sails, handle server-side events, etc.
