Comments are disappearing; it's not just you, and it's not just GT, it's happening on Balk Talk too. It may be blogspot, rather than disqus this time, since comments do seem to show up in notifications. ETA; Balk Talk mod k2b reports that it's actually a disqus issue, and they are aware of it. 2nd ETA; Disqus says that if you keep the page open and don't refresh, new comments will appear. I've also found that replies to me are showing up in notifications if I click the notifications button
