Phabricator, a software fabricator

Judging from the number of forced jokes on <a href="https://secure.phabricator.com/" rel="nofollow">https://secure.phabricator.com/</a> (needs login), it mostly seems to be a vehicle for bad humor.

Cool. Is anyone outside Facebook currently using this? At a quick glance, I like the focus on workflows rather than on features.
