Another visible change unannounced -- GONE
UPDATE 13 May 2010: According to Staff, this "feature" is for Admins only, and was not intended for public release. The bug has been fixed.
When it was being tested (I presume) a couple of days ago, it got the immediate attention of the K'nex community (who are, as you'd expect, inordinately preoccupied with status among their peers). Now that it seems to be "permanent," they continue to debate their tribal concerns about the information now available.
I'd be very interested in a "view from the top" posting about this feature (which I think is actually useful and interesting for data-mining), and how Instructables authors can benefit from it.
