well said. another important thing to remember is when jQuery came about interfacing with the DOM was really messy across browsers. Ajax queries as well. simplifying those, in my opinion, the killer features of jQuery at the time. Interfacing with the DOM was not even something that dojo, mootools etc were doing at the time. At least that part wasn't as obvious/easy in those frameworks.
