Here is a challenging way to learn how to edit Wikipedia: try making edits to the pages of people you don’t like. For example, I made a few changes to MN GOP Chair, Tony Sutton’s Wikipedia page last night to include his recent career change.:
The trick here is to make edits with a neutral point of view, which is difficult when working on pages you’re either closely affiliated with, or on a topic you don’t care for. In this case, it’s the latter.
I think my edits have helped grow Tony Sutton’s Wikipedia page with accurate and neutral information. However, I’m sure people more familiar with Mr. Sutton could build upon what I’ve added.
