Very funny. I hadn't seen this before. I particularly like:

>>Is it safe?

>>Uh… it evals both user input and random code, unchecked, from an external site. This is what security-minded folks would refer to as Very Bad™.

I do my best to make it safe(ish), though :) It only runs code samples that were posted before I made StackSort.

What if someone edits an answer posted before you made it?

Thank you for implementing stacksort!

It's not hard to imagine that stacksort works, but seeing it in action is really something different. It's scary and awesome at the same time.
