- It’s in active development
- It lets me maintain references to the real DOM elements, unlike JQuery.
- I can call into the library when I need it, no need to ask it not to clutter the namespace (MochiKit) with hundreds of functions.
- I am not looking to add glitz to my sites with a few lines of code .
I should note that this is by no means final, hell I was half way writing this about PrototypeJS before I dug deeper into MooTools and found it excellent.
