I don't have much experience with meta on this site, though I do remember this question. Per the accepted answer there, I agree that constantly coddling those who post new questions of poor quality, repeatedly, do not deserve ongoing attention and must have their questions closed.
First, I'd like to say a couple of things. I've gone through some life changes since I first got on this site 5 years ago. I've realised the real value of kindness, and I remember a certain senior player on the site who made life hell for me when I started out here (who is happily no longer around). I also remember a phase where I made life hell for some folks; I was dealing with my own issues then.
I appreciate that this is a gaming-related site and gaming has a whole set of stigmas around it: competitiveness, rampant bravado, intellectual duelling, etc. etc. I'm not boxing this site as being only those things, but they sometimes come through. Some apply to programming more broadly.
Do we have to criticise new users into hiding, and downvote their humble attempts at answers over the most trivial things, putting them on -1 before they can even think, or for things that are just unreasonable? We all know how the -1 dynamic works; once you hit -1, chances of getting any upvotes are pretty much annulled. That should be saved for worst cases.
I don't like this kind of thing when I see high-ranked members doing it, members with a vested interest in this site. I'm in my late thirties now, and I try to accept that I'm not one of the younger folk anymore, and I'm not new to my field, either. I have knowledge to impart, and with that seniority comes a duty to be kind to those less knowledgable and reputable... and often younger.
One must appreciate that tearing up and throwing out the window what people have put time and effort into crafting - their answers - is a slap in the face and gives you and the rest of us high-ranked users, a bad name... Why? Because that's the nature of privilege. I have had hateful comments directed at me before on this site due to my perceived privilege, undeserved. We are grouped that way in the newcomers mind... as top-rankers. In spite of the fact that the vast majority of the top members on this site are peaceful and at ease in their position - just as they should be.
Let's not be stackoverflow. We're a smaller community with far greater control over how we treat newcomers. We set the tone. It's one thing when we old hands duel amongst one another... quite another to pick on a greenhorn. Just please, think twice before dropping someone to -1.
