I love following best practices (No, I don't
cargo cult, they're really not the same) when it comes to programming. Least of the benefits is how it makes your code familiar and pro-ish. I found this collection of best practices for using jQuery that I want to share:
http://lab.abhinayrathore.com/jquery-standards/. If you write a ton of jQuery driven code (which I bet you do), spend some time grokking the wisdom and perhaps testing them.
I have a little free time, ping me in case you need a helping hand to improve your code base to comply with these best practices. It's free!
