Following an announcement on Sept 30 2009, Nexus friend grapher shut down permanently on Oct 7 2009.
We thank our many users for using and talking about Nexus.
Nexus launched in October 2007. It has generated over 500,000 friend graphs for 84,000 users. We shut it down because we no longer have
time to maintain or operate it. We're working on a lot of new things, but they're unrelated to Nexus.

People who have said things about Nexus (a partial list):
Nexus source code: Nexus-2009-10-14.tar.bz2 (see MUST-README.txt, DEPLOYMENT.txt files)
It's written in Python and JavaScript, but the code quality is "PHP era" (no test coverage, tightly coupled, other problems). It will take two days to get a Nexus instance running. If you do not know Python or cannot use a shell on Linux, it will not work for you. Also, I may have introduced one or two easily-correctible bugs when I removed all the garbage from the source tree.
