The Board of Supervisors plan to vote for an interim mayor was put on hold yesterday. The supes, it seems, want to first hear from the public. At Tuesday's meeting, according to BCN (via SF Appeal), John Avalos "asked instead for the board to take public comment on the selection process." Which makes sense. Lieutenant Governor-elect Gavin Newsom plans on leaving S.F. for his swank new gig on Jan. 3.
