So, the death of WSOIN (What Stack Overflow is Not) was intended to help reduce the snarky comment level. I don't see any diminution of the volume of sarcastic comments added to weak questions. I don't write this to reopen the debate.
Let me be a little more precise about what I mean by snark. To me, the issue is not a bit of humor or a slight poke, but the comments that very clearly call out the OP as some sort of idiot. As discussed elsewhere, these are particularly squirm-inducing when (one of) the OP's problem(s) is English language proficiency.
I used to be a fairly aggressive flagger of snark, but I got the sense (impossible to determine for sure) that the preponderance of my declined flags were cases where I flagged some snark as rude or offensive. I don't drop that many flags, and I couldn't explain the declined ones any other way. This led me to believe that the mods were setting a high bar of rudeness, so I stopped.
If you really want to reduce this behavior, you have to create a negative feedback loop, and it can't involve mod involvement for every single instance.
One option would be to add another flag option, 'snark'. This would make it clear that you don't have to insult someone's genetic heritage to qualify. Further, you could set a low bar for comment auto-deletion on these.
If this doesn't work, you could consider a rep penalty for comments that get flushed this way.
I see this as one of those consistency issues: if flushing WSOIN was important, then the job is really not done.
A little more in response to Shog9:
So, here's the interaction on my mind. A new person shows up and posts a crappy question. Fine. I stipulate. It's crappy. Further, I'm as pessimistic as the next person as to the chances that this person will pay attention to any responses and improve their question, let alone post a better one next time.
However, when the question is decorated with one, or often several, comments of sarcasm and insult, it gives a poor impression to other readers and supports a culture of jerkiness.
WSOIN at least was never personally insulting. It didn't accuse anyone of being a vampire, or stupid, or expecting other people to do the OP's job for the OP. Brusque, yes. If I were the team, and choosing between WSOIN and 'Only an idiot would ask that,' well, I'd choose the former.
Shog9's ideas about making comments go away at least limit the time window in which this is all visible.
I would point out that I've already seen comments today which are just like WSOIN only without the link to the more or less friendly explanatory paragraph.
...but I got the sense (impossible to determine for sure) that the preponderance of my declined flags were cases where I flagged some snark as rude or offensive.
- are you aware you can access your full flag history, with outcomes, from your user profile page? Then you can see exactly which were declined. Yours on SO should be at stackoverflow.com/users/flag-summary/131433 (only you and moderators can see it).3 + score / 3
flags from regular users on a comment will delete it. Usually I don't see more than 1 or 2. I'd say the community needs to be more aggressive about flagging snark and rudeness before mods even get to it.
