In a move sure to placate literally tens of people, I have removed the TypeKey requirement for commenting on the blog. As an alternative, all you need to do is enter the name of this blog (case insensitive) in the supplied field and your comment will be posted automatically. Otherwise you will not see an error, but your comment will be labeled as "junk" and will likely been discarded with the blog-spam. If you were one of the few who registered, your TypeKey account will still work and will let you bypass the filter.
Hopefully people will find this mechanism to be less intrusive than having to register with TypeKey.
Thanks again go out to Shaya for the plugin installation.
