There is the beginning of an answer to that over here:
We did post an answer to the mods' letters, @Zoe: in it we made reference to our next steps "entail[ing] structural change, [and that] it may take a little while." As Sara noted at the very bottom of her latest blog post, though, we're hoping to be able to share some progress on that next week. – JNat♦ 54 mins ago
(I bolded what I believe to be the important part).
Update:
In a later comment, JNat (tried to) clarify and said:
Sorry, @terdon-stopharmingMonica: I didn't mean to say that we'd answered the letters — I said an answer, as in we engaged in conversation, and as far as I know have no plans of ignoring it. Sorry if that wasn't clear enough. – JNat♦ Nov 14 at 20:45
