Then add some concrete reasoning and comparison. Do some work. Fuel the conversation. Otherwise the only thing left is the assumption that you do not understand the differences between the two tools. I'm a YUI-hater and jQ-fan, so I appreciate what you're trying to do, but it needs some substance.

edit:

I don't mean to come off dickish. I started out writing my own AJAX libs in 2002-2003, started stealing some good ideas from Prototype in 2004-5, eventually trusted my fate with jQ in 2006, and have facepalmed every time anyone recommends we use YUI since the day of its release. It's like the worst of both poles...it is neither a fluid, lightweight swiss-army knife like jQ, nor a well-constructed application framework like ember. Instead it always seemed to be a rigid set of off-the-shelf components that appealed to people who liked to talk about design patterns but not actually build anything.
