Get a job!
 

Ever wanted to work on Allakhazam? Thottbot? Wowhead?

Zam is hiring and has two full time positions available, one for a Programmer and the other for a Designer. If you're interested in finding out more about the requirements check our Zam's job opening page.

If you - unsuccessfully - try to view that page in the Opera browser you can see why their are looking for a web designer. :D SCNR

That's a pretty cool job opportunity right there.
I wish I knew a little more for each of the categories listed. I know a bit a bout a whole lot, but probably nothing on the "extensive knowledge" level for any particular topic :D
