Adobe laid off 150 people in 2001, and Macromedia laid off 170, which was 10% of the staff at the time (which was partially because of a merger, but if things had been booming I don’t think it would have been nearly as high). So layoffs are hardly unprecedented. If Adobe and Macromedia survived the dot.com implosion, I’m sure they’ll do ok this time around.
