Just saw this and thought it might help out:
Google Blogger has recently altered their “threading” causing most people to experience problems with loading the blog or leaving comments. To fix this, simply change your blog option from embedded comments to pop up comments. Here is how to do it:
1. Log in to the dashboard of your own blog.
2. Click on “Settings” and then click on “Comments.”
3.Under the “Comment Form Placement” choose “Pop-Up Window.”
This will allow users to see your blog properly and to add comments. It won’t change others blogs and what you can see or comment on, until they make the same fix. Pass the message around so that everybody can make the changes for themselves.
