After a discussion with one of our intrepid readers, followed by some research on Disqus' forum, it's now clear that the new comment system is not compatible with the Safari browser. What this means is that when clicking on the comments link on the main page, neither the comments nor the comment entry box show up on the individual post page.
If you run Safari on a Mac and are experiencing the same issues, then you might want to switch to Firefox until Disqus addresses the issue, since that seems to fix the problem.
Of course, if there are Mac/Safari readers out there who don't have any problems with the comment system, then please give us some details as to what version(s) you're running and any special settings or configurations you have set so that others could benefit.
We now return to your regularly scheduled blog.
