queenbutterfly - if you mean the previous entry, that was me, and I made it private on purpose, and requested it be taken off RC. I actually put a blurb at the beginning of the entry explaining why (which could be seen on the part of the entry that is seen on the main page) so that people would know. It wasn't private when put onto RC - I made it private afterwards, because I hadn't wanted it to be on RC. I contacted staff to ask them to remove it, but they didn't happen to be around for a few days, so the entry remained.
None of the other RC entries have been private lately. However, plenty of people have the setting that their diary cannot be read by people whose diaries they can't see (which is a fair-enough setting to have, even if you are on RC) so it will make sense that people with FO diaries won't be able to read all the RC entries. Nor will visitors to the site who don't have diaries.
Personally, I'd love for RC entries to have public comments - since RC kind of makes it a bit of a community discussion, so it's kind of boring to get involved in reading and commenting an entry with private comments. But at the same time, that's a setting that some people have for various reasons.
I suppose the only foolproof way to get around this is to insist that only people with the lowest possible privacy settings can be selected onto RC.
