Discuss JS Errors
Some JS errors out there commonly happen for common and not-so-common reasons. For example, jQuery sometimes doesn't load, and page breaks with "$ is not defined" etc. What would be nice is that you provide a discussion forum around any error, so that I can read it up to know its possible causes.
That discussion can be public. All errorception users can comment (e.g. how I solved this one) This might turn into a good "why that JS error?" resource.
