Push Notifications with IFTTT
Apparently IFTTT can monitor RSS/ATOM streams (like mine) and perform an action for new items. That means that I can have TradeSocial output an RSS feed for the system as a whole, for the feeds of individual users, and for @replies. Then I can tell IFTTT to look at those feeds and (send an email -OR- send a push notification -OR- Post a Tweet -OR- etc.) any time one of them changes.
