I run BloopDiaryBasics, under the direction of Steve. I updated it at the beginning of this month. I check it all the time for messages and comments, so rest assured that those people get the help they need.
I generally only update it when a) a new feature comes up or b) there's an onslaught of questions about the same thing (e.g. BloopPlus points). Sadly, the diary used to have about 40 entries but they were all lost in the crash. However, many of them are irrelevant now, with the removal of old features and a shift in the focus of the site.
If you, or anyone, thinks BDB should include something that it doesn't yet include, please let me or Steve know.
I have a feeling that Bloop Help Desk, while it has the best intentions, will eventually be updated as infrequently as BloopDiaryBasics, because you can only talk so much about the way Bloop works before you, literally, have nothing else to update about. And I just don't see the point in the duplication.
