This announcement of 4,000 more layoffs at American Express made me think about layoff trackers.
I found a few and am listing them here.
Forbes Fortune 500 layoff tracker
Techcrunch has technical layoffs.
We have a layoff tracker blog.
Another is here.
A site devoted to layoff and employer stories, Telonu.
Slate has an interactive map of the job losses.
When you see this you will realize unemployment is at crisis levels.
