I'm not clear on the difference between a trigger and a quick trigger. Is it just that regular triggers are run in batch jobs, and quick triggers are processed individually?
Most of the triggers on IFTTT require polling to receive updates. We poll the sources roughly every 15 minutes.
Quick triggers, on the other hand, are event-driven.
So, for instance, if you had a task that was "IF I send IFTTT a Google Chat THEN post to Twitter" we'll now post your tweet within a couple of seconds (vs. before it would have been within 15 minutes)
