This is the first I've heard of Meteor APM, looks awesome!

This line confused me:

> Using simpler queries will usually mean there’s less work for Meteor to do to decide if a change affects it.

Is this right? Previous Meteor optimization articles I've read have stated the opposite, and all my years of database development have told me to avoid 'SELECT *' and other simple DB calls like the plague. But maybe I missed something in the article that explains this.

Thanks Tom and Sacha for your great contributions to the Meteor community!
