JQuery is great for DOM interaction. If you are making a complex web app, you should be using a framework designed for that and DOM interaction not through the framework is going to cause problems and convoluted code with side effects. If you are making a web-site and not a web-application, it's great. A lot of pain comes from a project that evolved from a complexity where JQuery was a good choice to a complexity where it is not a good choice, and the work wasn't done to convert the existing stuff.
