I agree whole heartedly thats what i am getting at... jQuery succeeded not by trying to be everything but by trying to solve a real straightforward common issue that affects big projects and small projects, super senior developers and junior developers...

I am not suggesting we go back to jquery, i am suggesting that the next really successful widespread framework is going to get adopting by solving a specific widespread problem in a way that appears simple to the consuming developer...

as for jquerys run, it had the best run of any javascript framework in history, by a wide margin... and it really got supplanted not by other frameworks, or even by just losing popularity... it was so successful that it drove all the modern browsers to adopt its api and build it natively into the browser engine...
