given a recent run in with abusive trolling, i thought that it would be useful to give a comments policy. we welcome comments at this site and at my personal blog site. please feel free to comment as you wish. however, comments are subject to moderation. first, except in very rare cases, comments from anonymous users will not be accepted. if you have something to say stand behind it responsibly. otherwise, do not join the fray. second, comments that include racially abusive language will be trashed immediately. third, ad hominems are sometimes entertaining, but do keep them witty and to a minimum. please keep both of these guidelines in mind. thank you
