It was brought to my attention the other day that Blogger's 'Comment' feature did not permit people to comment unless they were Blogger members. And I certainly never intended to shut any voices out. So to remedy that problem, I've switched the site over to Haloscan comments.
And old comments haven't been erased. They can still be seen by accessing the blog archives. And you can still use Blogger comments on old posts (in case you happen to feel compelled to do so).
