It solves the problem people have with /qa/ threads dying too fast, and the issue people have with not feeling that they can create as many threads as they can. /jp/ created threads only bump off /jp/ threads, which are more dumb and people don't care as much about or think will fit all that well or meet the quality standard of /qa/. While on the other hand threads that are made on /qa/ aren't killed off as fast. This was an issue that people had brought up for a while, suggesting all sorts of fixes like half-bumps or semi-stickies for the better threads, but unintentionally they were solved by the inclusion of a secondary board and overboard. Limiting the potential harm that people suggested a second board would cause is also a plus.

What are your thoughts on the use and benefits of the overboard, and secondary boards in general if you will. Personally I believe that the secondary boards are a great addition that futureproof the site from running into issues.
