Well, for some time now i have been using TweenLite and especially TweenMax as my AS3 tweening engine. Jack has made an amazing job writing these classes and a real service to the Actionscript community by sharing them like this.
Now, i searched google for the terms “green” “sock” (which is the name of his blog) and the site was the 5th-6th result. And since this is unacceptable, there you have it; a whole blog post to boost by a tiny bit greensock‘s pagerank!
