Since I now have comments by Haloscan (a few have commented there, and it's a little more difficult to get to), I have disabled comments for new posts. Don't know if it will affect your ability to comment on old posts, and I hope it works correctly.
Maybe I'm the only one who doesn't know his, but assuming that there are some out there as computer illiterate as I, to comment, you now have click on the time of the post, which will lead you to a page showing only the post, and a link to comment. Let me know how you like it.
We shall see.
UPDATE: I've had fewer comments, so a little reminder: while Blogger comments have been disabled, you can still comment. Just click on the time-stamp, which will give you access to Haloscan comments.
