Try coming to the page again and wait for the page to completely download before scrolling down. If you scroll down before the bottom bar says "done" then the page will smear down with endless repetitions of the first sentense.
For comment-writers: If you're a blogger yourself then you better transfer to the new Google-influenced system ASAP. If you're on the new system then when the comment box asks for your user-name and password you'll type in your new Google codes. The new user-name is always an internet address like email@example.com. The password is the new password you invented for Google when you tranferred from the old system.
If you want to comment but you haven't switched to the new Google system yet then I suppose it's OK to do everything the old way.
The new system is both better and worse. You get more bandwidth and it publishes real fast but it has some annoying idiosyncricies. On the comments page I'm constantly having to click off windows that warn me that letters might originate from unsecured senders.
