Help defend Monica from defamation!

Stack Overflow, Inc. must repair the damage caused by their libel against Monica Cellio, cooperate with the community, be willing to talk, treat users with respect, learn about the world outside the United States, open the governance of the sites.

I am a developer, mainly on embedded systems, with a computer science background and security and cryptography leanings by trade. I also have interests in various other topics.
