blazer rules, been using it since day one of our startup. it's great for situations where someone on the team needs a graph or CSV download of what's in the database. saves so much time and effort compared to writing code to do the same work. we have written over 100 different queries and dashboards in blazer and use it daily.

ankane is a true wizard; dude has written so many other fabulous tools like searchkick & chartkick.
