Hi,
Users of the future Wikimedia Phabricator will have a very simple and straightforward interface to create and edit tasks. Bugzilla's UI was one of the top complaints from new/casual users, and we can fix this in Phabricator easily. Currently we are testing this setup in fab.wmflabs.org, where you can see an example:
http://fab.wmflabs.org/maniphest/task/create/ (imagine that the "Points" field is not there).
Advanced users needing to prioritize tasks, assign them to someone, and resolve them can join the Triagers team in order to get the additional permissions:

We are still fine tuning this process at http://fab.wmflabs.org/T64 -- your feedback is welcome.
