Through the medium of the World Wide Web, anyone can become a columnist. The challenge is to say something without seeming egotistical or (worse yet) irrelevant. In order to minimize the latter concern, I ask for suggestions of topics to pursue; for the former, I will collect responses to these columns in order to present a variety of opinions. Columns and responses will be added on an irregular basis, so check back every month or so to see what's new.
