Good thing I'm still stalking around here occasionally.
Specifically for questions like this, too. :P
No, we're not dead. We moved. Take note of this post:
http://hypno.booru.org/index.php?page=post&s=view&id=10289We moved to a new site with a new booru-like gallery software.
The new software doesn't have any anonymous privileges (other than viewing content), which is the only real downside. What it does have, though, is a million new, cool features that we're STILL discovering every so often, such as a mail system, user avatars, a better blacklist system, tag autocompletion (makes tagging and searching a snap), etc.
Refer to the post I linked above for the URL. And, uh, prepare for some reading. The URL goes to a large, but important forum post on the new site outlining new things one should know about the new software, and some policy changes.
