Good question! Firstly I think the term 'SNOT' should be clarified-- are we discussing techniques that change the orientation of a brick, or the morass of 'tiled all over' MOCs that seem the standard on MOCpages (and the builders who argue against exposed studs in general)? Firstly, I'll say that I have no right or even desire to tell others how to build.
On SNOT and landscape:
I have used SNOT to build
rocks, water, and
snow, reasoning that repetition is a good way to validate any techniques's existence (meaning: these used as SNOT work better in a big scene than the same technique would look in a vignette for the simple reason of conservation of detail) Complicated, eye-catching techniques can draw focus away from the heroes in a smaller scene but become nearly ubiquitous when used as a backdrop for a castle or tower.
On SNOT and detail:
The more the better! My building style is almost painfully busy, and complicated, parts-intensive, but
flashy SNOT can, for the same reasons above, focus attention on the part of a building I want to draw attention
to-- the roof in
this MOC is a good example.
Other problems are best solved with SNOT!
Finally- sometimes SNOT is just plain cool. My tag is made of SNOTted tiles and bricks!
