Dear IamAmerica,
This has already been discussed. There are many reasons why anonymity may be important in a forum, and in other places.
Here is one of them (copied from the 'rules' thread);
Many users are teachers who would not necessarily want their private
views to carry the added weight in the minds of their students that
their views might if they were accompanied by the teacher's name.
Teachers have a responsibility to ensure they do not unduly
influence the beliefs of their students on certain matters. They may,
however, wish to prompt students to consider certain things the student
would not otherwise have considered. By posting anonymously, issues can
be raised and opinions voiced without carrying the 'authorative'
emphasis a teacher's name might impart.
