Commenting Policy


The commenting system uses DISQUS which requires that you log in in order to post comments. You can either create a unique account with them or use a third-party log in. Please see their terms of use and privacy policy.

By signing up with DISQUS and choosing to use the commenting feature on, you agree to these terms and protocols:

  • Comments will be relevant to the topic of the article they're posted on
  • Comments will be constructive only, even if critical and challenging another's viewpoint, and will not include any defamatory or derogatory language (i.e. no bad-mouthing or debasing other users or researches, or using language such as "fucking", "bullshit", "asshole", "idiot", "moron" or the like... we want mothers and children to feel equally comfortable here!).
  • It is OK to post links to personal projects and sites within reason, but not OK to saturate comments with self-promotion.

Marshall Lefferts and The Cosmometry Project reserve the right to prohibit commenting by any user who violates the terms and protocols of this commenting agreement. To report abuses, please write to
