Probably would be interest in this if it were created. There just needs to be a critical mass of jobs posted on there to get people started using it. Then usage will snowball.
Once an EA jobs board/wiki is created, email the organizations listed above, asking them to put their job ads on there (in addition to on their own sites)--or at least links to the full ads.
Sounds like a perfect project for .impact!

And, yes, I'm interested. :)
