That's a good question. To me, the difference is that when we're writing software and just trying semi-random UX ideas and implementation approaches out, we don't have any real constraints that we're genuinely bounded to. So, yes - throwing crap afu the wall is an optimization process. It's the other half of the above definition that it misses, IMO.
