I'm not sure if it's because of 3.4.2 upgrade, but my comments are not showing up. I have them turned on in the dashboard but nothing shows on teh actual post. Here's a my most recent post with the issue http://doodiepants.com/2012/09/15/crazy-group-of-vets-attempt-baja-1000/
I have all caching turned off.
Also, I have "show faces" unchecked and as you can see....faces are showing.
