So the gospel on pulling associated records that you know you're going to use is to use :include because you'll get a join and avoid a whole bunch of extra queries: Post.all(:include => :comments) However when you look at ...

I was wondering if anybody knew what library (jQuery, Prototype, any) was used in the frontend, and/or which (if any) plugins/gems were used in the backend. For reference, you can find an...
