Inheriting raw access to the heatspace matrix instead of using a
method to get points made a big difference.  I'd argue that's moving
in the direction of `algorithmic' because it involves some thinking
about how pieces fit together. 

I think that a measure of distrust for `abstraction boundaries' is
appropriate, in general, but that over time one can learn to trust and
invest-in certain abstraction boundaries.  Otherwise you can get stuck
on local maxima just jumping through hoops.  But before I reveal too
much of my own psychology, I'll stop there.  ;)
