One of my primary interests is the expansion of baseball articles on Wikipedia. WikiProject Baseball is doing some cool things, including this baseball resource library. One goal of mine is to expand the WP entry of every Baseball Hall of Fame player entry to at least []. In addition, I have strong interests in nursing, psychology and medicine - especially biographies within those subjects.
I've also helped with biography articles associated with my alma mater, Texas A&M University. The cool thing is that I could edit something completely different every day and still never run out of things to do. I occasionally participate on the Spanish Wikipedia. I also operate an alternative account here, User:EricEnfermeroMobile, for use on public computers and mobile devices. With my standard account, I have a tendency to trigger the rollback function when my mobile device is in my pocket. :)
