Also, middle-clicking a link opens it in the same tab/window. Is that intentional?
Could be changed to only preventDefault/stopPropagation if it doesn't match one of the specially tagged links, or by setting up a different selector for the specially handled links.
Mislav wrote a great post on how to do this robustly: http://mislav.uniqpath.com/2011/03/click-hijack/
Hope that helps!
