I have a wide and varied set of interests in broad categories such as sports and computers, and other various activities. I can judge my interests by my obsessions over the years. Here is the laundry list (in order of length of time spent doing it): Playing basketball, genealogy, flight simulation, racing simulation, computer games, golf, computer repair business. And I'm sure there are others I am forgetting at this point.
I believe I'm a newcomer to Wikipedia editing - but I've done this kind of work in my professional career many times. I have a good eye for realizing content organization and layout. And am fairly average in everything else.
I do believe that a great piece of writing involves much collaboration. And it's really no different here.
