I recently changed the comments to disallow anonymous comments. This was not meant to discourage discussion or opinions, but I simply do not want posters who have no identity at all. I encourage people to use aliases if they'd like. I value the ability for us to be somewhat anonymous online, but do not believe in commenters being a blind face with an opinion. Logistically, it is also hard to keep track of which person said what when everyone is anon.
Thanks. Happy commenting.
