@Heffboom_Konijn Not really sure; that seems to vary per user. Certainly usage has gotten muddled. :-/
@orrery @emanate @Heffboom_Konijn I use it pretty much exactly as I used to use the cut tag back on LJ--trigger warning, long-post warning, you-might-not-be-interested-in-this-subject warning--and sometimes just to be silly, or because I want to make sure that the person reading is willing to make the minor investment of clicking a link before seeing what I wrote, rather than glancing across it randomly.
@Heffboom_Konijn @green @orrery @emanate It seems entirely reasonable to me?
@green @orrery @emanate @Heffboom_Konijn one thing I've seen done is people actually writing out "CW: whatever" in the cw line when it actually is an especially serious business warning
