Ask HN: Is anyone else having a problem replying to the job threads?

Was going through the threads by WhoIsHiring, and it looks like they won't let me reply to a lot of the posts. There seems to be a few random posts with a 'reply' link at the bottom, but 70% appear to have this missing. Also, the 'Add Comment' textarea at the top is missing. Is anybody else experiencing this? Did I miss some announcement about this going into affect? Example link: http://news.ycombinator.com/item?id=2396027
