Joe, Shann got that a little wrong. Hinting wasn't done away with when we brought in the editors (which was near three years ago). It was after we tried to run the Challenge over two weeks instead of one (back in October-December 2011) to lighten the workload. When that didn't go over well, and we brought it back as weekly (a year ago), we decided to go straight to brick throwing once the judges have their winners (to just cut out that one extra step with hinting).
Although the task of posting for hinting time and then brick throwing was not a huge thing, it was a problem when the judging (or finalizing) was taking a bit longer than expected. Delays do happen now and then, so going straight to brick throwing just simplified things generally.
But we definitely still have brick throwing, and that's happening for FLAT right now:http://bit.ly/UYawZj
