We got accepted for a 45min session on Wikimedia's move to Phabricator at https://fosdem.org/2015/.
Rough plan for content:
* Reuse stuff from https://blogs.gnome.org/aklapper/2014/12/17/welcome-phabricator/
* The problem that WM had
* Discussion, RfC/process, decision to investigate/move to Phab
* The process
** Upstream
*** Clear prioritization of tasks; what upstream is not interested in
*** Fast feedback to contributors on blockers or how to address an issue
** Bugzilla and RT, the unexpected stuff
* Achievements / what we like
** More teams in the same place, collaboration, community vs devs, ...
* Future plans
** Code review etc
** Wikimedia vs upstream: No releases; pulling upstream and need to test (CI)
* (FOSS: What you might dislike?)
** Relies on Flash for notifications (to be replaced by WebSocket; 6559)
** [[ https://secure.phabricator.com/L28 | CLA ]] for upstream code contributions (judge yourself)
* Enough time for Q&A
