@Jon z: Yep, minifying the JS will definitely help and I do mention that using a CDN version of these files would also help make the payload less bulky and make use of cached files.

It's true that Edge only really works with jQuery, although as long as the jQuery code is namespaced there's no reason you couldn't use another framework, although that would just contribute further to the previous issue of file size / payload. I think mainly jQuery is really the most popular JavaScript framework and as such is the reason it's getting used here.

Regarding my spam test, I would presume the temperature of ice is the same in both northern and southern hemispheres? ;) (I'm guessing you misread that as "Is *it* hot or cold?" – I can see how that would be dumb!)

Thanks for your comment!
