I'm bringing a new intern up to speed, and while I was showing him how to diagnose one particular wine bug, I recorded the session on a web page, http://kegel.com/wine/bug30486.html
It occurred to me that recorded sessions like that might be useful to other beginners (above and beyond the more structured wine developer doc), so I created http://wiki.winehq.org/DeveloperExamples and linked to it from there.
Does that seem useful, and are there other tutorials that could be linked to?
