Comments not meeting the guidelines may be edited or deleted.  Frequent violations of the guidelines may result in a ban.  Merely disagreeing with me is not going to result in your comment being deleted.

Other notes:

• I work on this blog in my free time.  I’ll try to read every comment but I may not reply to every comment.  If I do reply it may be delayed or not particularly detailed.
