Someone could make a css crime version of this post where the "show post" button is actually clickable and then reveals in the bus a bunch of the tags you would see on hidden posts.
The NSFW acronym never made sense to me because if I'm goofing off on the internet at work I'm ALREADY being careful, but those poor strangers on the bus/behind me in line at the supermarket/walking by me at the coffee shop... those I worry about.
