My name is David King. I run a Wikipedia consulting business called Ethical Wiki. In this role, I have authored more than 30% of Wikipedia's Good Article-ranked company pages, and brought many others up to the GA standard.
I also used to be an active volunteer with almost 40,000 edits. However, you can safely assume any recent edits are in my Ethical Wiki role and are made on behalf of the article-subject, unless I mention otherwise. Finally, I am also a licensed attorney and work for myself at King @ Law. One of these days, I hope to use unfair competition laws to force black-hat Wikipedia services to comply with the transparency requirements in Wikipedia's Terms of Use.
