I've noticed recently that a number of you have been reposting your comments by breaking them up into two or more parts.
This is to let you know that the "requested URL too large" message you sometimes get from Google when you write a long comment is misleading. I am getting these longer comments and could simply moderate them as they are. Give it a try and see whether your long comments come through without your having to go to the trouble to break them up and re-post. As it stands, I'm simply deleting the duplicates, but it does worry me sometimes that I might accidentally delete some part of what you have to say.
I've learned to ignore that "too large" message. The comment is always there anyway. Of course, that's easy for me to do, because my comments are unmoderated, since I'm the blog administrator. So I can simply go and look to see whether it posted. I'm sorry that this isn't as easy for you, my valued readers, to do. Unfortunately I have reason to believe that it's still a good idea to keep comments moderation turned on.
The only message I've ever gotten that really meant that my comment didn't post was something like, "We were unable to fulfill your request" or words to that effect. In that case, the comment was really simply lost, and I could not even use the back button to recover the content and break it up.
But the white screen with the "requested URL too large" message appears, so far, to be functionally meaningless. So you can save yourselves some time by just waiting to see if your long comment appears before trying again. Thanks!
