I've read the parts of this which define the language (through p.190),
now, but will comment on the other thread devoted to Gala.

Unfortunately, I think the answer to "how many people are using is" is
"none":"

  http://ai.stanford.edu/~koller/gala.html

This page says that the version of Prolog which Gala relies on isn't
available anymore. It does make me wonder what exactly they were doing
which prevented them moving to a Prolog interpreter which is still
maintained.
