Given the concerns over lack of communication, I wonder if that was the right move. I can see how hard this would be to manage on-site communications with everyone mass-downvoting anything from /u/kn0thing or /u/ekjp though, so I certainly don't have any better ideas.
At the very least, he could have posted beforehand to say "we'll get back to you about this on Monday."
Also, I don't understand the excuse about downvoting as a reason for not saying anything. If she says something worthwhile people will pick it up and link to it. So far, much of the reason they are getting downvoted is that they aren't saying anything meaningful. This thread was an exception.
