Agile Web development with Rails : Rocks

It is being more than 3 months I am using RoR and till now I was solving all the problems using public forums/google/RoR irc channel on freenode but since(2 weeks) I got this book "Agile web development with rails" and now around 70% of problems are solved by simple search in this book, Dave and David has done excellent job, real must for anyone who plans to adopt RoR(RoR culture :-) ).
