So I need to load an additional js framework in additional to whatever one I'm using so that I can run plugins from yet another framework? As much as I <i>love</i> javascript, we still have to remember that most people don't use the kickass speedy browsers that we tend to (Chrome, Safari). Depending on your audience, you have 30-40% of your audience using Firefox. That's pretty good, but things get boggy with FF and too much js running.<p>If you're building a web application, i.e. something like Gmail, then you need to pick one js framework and stick with it. Make your code as efficient as possible. If you are just building a regular web site, do you <i>really</i> need to have all of that extra overhead for a couple of widgets?<p>Treat js development like da Vinci treated marble. Cut away until you find the statue in the marble.
