You know you're in a healthy community when people randomly offer limericks in return for code reviews.
And it's especially healthy when it randomly spills over into IRC:
There once was a dude named Crell
He immersed himself in database hell
Then he pushed PHP 5
And the lists came alive
And now all our database handling is swell.
And from Jeff Eaton:
There once was a coder named Crell
who descended to PDO hell.
Though objects he loved,
chx pushed and shoved.
In the end, the two did show-and-tell.
And that is how DrupalCon is organized. :-)
