The script scans the page for any links pointing to *.wowhead.com and adds tooltips when they are moused over that display the item info. (Demo)
A couple problems I can see with this are:
- Only useful for World of Warcraft questions, and a waste of bandwidth on others (although presumably it would only be loaded once, then cached). Perhaps it could only be loaded if the question is tagged world-of-warcraft?
- Depends on an external script that isn't hosted by SOIS, Inc, unlike the Mathjax library used on Math.SE/Physics.SE. Possible security risk. (What if Wowhead gets hacked/turns evil and their JS is modified to serve popups?) Wowhead does provide raw XML data, so we could host their script locally or roll our own.
Regardless, it'd be incredibly useful to be instantly pull up more info when reading posts like this one.
