When I like this blog best is when conversation takes place among blog contributors and commenters.
One barrier to conversation is the tendency of some to move quickly to judgement, rejecting different opinions and perspectives. But other than encouraging people to keep an open mind and listen to others' ideas, there is not much we can do about that.
Another barrier to conversation is the habit of many to comment as "Anonymous." I understand why people comment anonymously: for some it is because of technology issues; for others out of a need or wish to remain anonymous. But in both cases, nothing prevents you from creating an identity for the purposes of discussion on this blog.
For example, if you comment as "Anonymous" because of technology issues, you can still sign your name at the end of your comment, as Gabrielle, Leslie, and several others have been doing recently. And if you comment as "Anonymous" because of a wish to shield your identity, just create a blog identify, whether it is another person's name or a made-up name, and use that consistently when you comment.
If everyone identifies themselves in comments, whether by a real or fictious name, it will make it much easier to respond to individual comments and maintain a feeling of conversation in this online discussion place.
