  - Reviewing code is much less daunting
  - Reviewers give more detailed feedback
  - Developers get feedback on lower layers (such as model definition) before writing a ton of code that depends on it
  - Reviews come quickly enough that developers don't need to switch to another project before continuing

  - Use feature flags to commit unfinished features to master/trunk without exposing them
  - Submit model changes as their own diffs, then API changes, then UI changes
  - As you work on a feature, pick out parts that seem ready for review, stage and commit them, send for review, then branch again from that point and continue working.  This takes a decent amount of git-fu, so train folks accordingly.
