Ryan Kuder has launched a site called the Purple People Collective (ironic that the initials are PPC). It has listings for work for laid off Yahoos.
Others who have been laid off are welcome, as well. Most of the listings as of this post appear to be for tech-related jobs.
On a personal note of encouragement, I've been laid off a few times and every time the next job was way better than the last. My husband was laid off at the beginning of this year and his "new job" is so much better.
Hopefully, the same happens for ex-Yahoo's and others facing the same fate. Don't forget to check out the Search Engine Watch Job Board for opportunities as well!
