In my office, full of engineers and sysops, we figure that stackexchange has already died.

Here is example of the day (far from the only one): http://serverfault.com/questions/542572/jemalloc-error-making-redis-on-centos-6-4

The only suggestions for improving the original question.

What is the point of participating when the powers that be are so full of.... power?
