Good for you! Even though I have been experimenting with Meteor for a long time (and have one deployed application) I read your book while it was online for free and I picked up some good stuff I didn't know before. Thanks!
I really enjoyed Discover Meteor. I bought it myself when it was originally released as my interest in JS increased and found it quite rewarding, and very well documented. I wish it went deeper into testing, but for a quick bootstrapping into MeteorJS nothing is better and it is a fun project; especially with the advanced sidebar sections.
