The posts placing highest value on aesthetics are probably in best agreement with the traditional definition of fine art.
It may actually be easier for us to agree on what 'fine art' and 'aesthetics' are not, than to say precisely what they are. (Critical theorists and artists themselves have wrestled with these definitions for a very long time, so... patience, patience y'all...)
I think we can probably agree that commercialism, mass production, imitation, etc. are not consistent with the ideals of fine art. That is progress.
Now, some may argue that fine art cannot be created in a casual way (i.e. in 'snapshooting' mode) but... I am not so sure. I find my own thoughts can front-load a photograph so much that whatever modicum of fresh aesthetic was present in the scene gets completely obscured. There is something very liberating about snapshooting sometimes and appreciating a scene for itself, as its own aesthetic.
