Post a Comment
We reserve the right to delete comments, but the failure to delete any particular comment should not be interpreted as an endorsement thereof.
In general, we expect comments to be relevant to the story, or to a prior comment that is relevant; and we expect some minimal level of civility. Defining that line is inherently subjective, so try to stay clear of insulting remarks. If you respond to a comment that is later deleted, we may take your response with it. Deleting your comment isn't a personal knock on you, so don't take it as such.
We allow a variety of ways for commenters to identify themselves; those who choose not to do so should take extra care. Absent any prior context in which they may be understood, ironic comments may be misinterpreted. Once you've earned a reputation for contributing to a conversation, we are likely to be more tolerant in those gray areas, as we'll understand where you're coming from.
