Leave REST aside and embrace Socket.io, ZeroMQ, RabbitMQ, Erlang, XMPP; explore realtime as the next step in app development. Realtime is not only for chat apps. Remove polling from the equation forever.
Remember this: the fact that you understand something does not imply that you have to agree to it.
Of course, please know that as you will grow old, the number of things that qualify as new and/or important will drop dramatically. Prepare for this. It is OK to weep silently when you realise this.
