Ask HN: What happened to jobs.usethesource.com?

Hi, Periodically I would check in on jobs.usethesource.com even when not looking for work. Before that, I used it when it was just usethesource.com. A while ago I noticed that the site was down. At the time I thought it was just a temporary disruption, but now I've realized that the site is gone gone and the associated Twitter account is also gone. It is no big deal, but admittedly I'm a little curious as to what happened. Also, it was an Arc-based site, right? I vaguely recall it using the HN source code.
