I remember the days when MooTools was hot^H^H^H^H useful enough to be bundled in Joomla.

Learning JavaScript while fiddling with it was really fun in 2009 when I was about to graduate from high school. Aaron Newton's jqueryvsmootools was an eye opener when I first read it and David Walsh's blog was really helpful in the early days.

I still like to follow some of its contributors (mainly Dimitar Christoff and Chris Pojer).
