I think you should start one. I'd be happy to help.
I'm rather proficient in C; somewhat literate about postgres' GIST
stuff (I think a couple of my bugfix patches were accepted in postgis);
and deal with a big database doing lots of similarity-based searches (a
6'2" guy with light brown hair being similar to a 6'1" guy with dark
blond hair) - and am experimenting with modeling some of the data as
vectors in postgres.
