Here is the schema, and a diff of me trying to fix the problem (now gets
KeyError: 'keyword').  The schema was ported from 0.8 (I added a topic
list to user record, and users can only see their own topics unless list
is empty), so I probably broke it.  But how was it working all this
time?  I have to catch a train in the morning, so I won't be able to
check in again until tomorrow (via mobile hotspot on the train!).
