Javascript library for web interface

[Brad]

I started poking around at the javascript libraries for web UI's. We have talked about JQuery in the past. There are some more advanced JS libraries that have some nice features and OO basis such as MooTools and Dojo Toolkit. I like these libraries better than just JQuery as they would be more structured than JQuery. Dojo Toolkit looks to have more documentation behind it and also has a mobile library as well.

Any Thoughts?
