[wvenable]

jQuery is a much smaller scope than Prototype or Mootools -- it doesn't try and enforce a JavaScript framework. I previously avoided it because it provided so much less general programming tools than the alternatives.

However, in the years since I made some of those technology decisions, jQuery has become the leader and thus more and more 3rd party technologies have been built around it.

I've recently switched to jQuery from mootools but I had to seek out a lot of plugins and other libraries (and build some stuff myself) to reach the same levels of capability but ultimately I'm happy with the results.
