My chief interest in Wikipedia is its immense value as a history resource. When I studied the subject at university it was my first port of call when tackling a new topic.
In creating and editing articles I try to place accuracy and objectivity at the forefront of my contributions. In particular, I value well-sourced references over unattributed assertions.
My main beef with Wikipedia is how it has become a repository of highly detailed trivia pertaining to popular culture. But there is enough good stuff there to keep me interested.
