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. I started What Wikipedia is not (organizations), which summarizes community consensus on key issues affecting company pages. 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.
