Me: occasional Wikipedia reader/editor. Took a user name because I wanted to create an article about a news story I'd read about Weldon Angelos' first hearing connected with concepts of truth, proof, justice, reasonable doubt. (note: Weldon Angelos has been freed! I wonder if our article helped. Of the many issues we highlighted, a crucial one was that 'reasonable doubt' is not invariant of context.)
Also interested in preserving the natural environment though it's not clear how Wikipedia could help with that.
