Maybe it wasn't express, but implied. There are a few simple drivers for this: 1. Push messaging is intermediated and relatively slow and expensive; direct communication is always cheaper and faster 2. ...but only when you already have a connection; maintaining a long term connection from multiple clients is very expensive. Therefore, push is best used when you don't have a direct communication channel open to your site. Use direct connections when available, but let them close and use push when you aren't actively using them.
