      GetTor usage.
    - Filed https://bugs.torproject.org/30264 to discuss how to proceed
      with default bridges.
      - We may want to add more default bridges.  Some are saturated,
        other aren't.
      - Cohosh suggested to use potential new default bridges for
        experiments in:
    - Started writing code for https://bugs.torproject.org/9316 to
      export BridgeDB metrics.
    - Mostly finished https://bugs.torproject.org/28655
      - https://gitweb.torproject.org/user/phw/bridgedb.git/log/?h=bug28655
      - Estimated how many bridges would be affected by this patch.
