It’s almost over now (ends at 3:30PM Central Time), but The A.V. Club is running an open forum about the upcoming changeover to Kinja, in case anyone’s interested.
One interesting note - they’re porting all the Disqus comments to Kinja and giving commenters the ability to claim an automatically un-greyed Kinja account. That should ease some of the panic over there.
I’m going to see if they’ve said anything about merging Disqus comments into an existing Kinja account.
