There are a handful of new users coming to our Tridion StackExchange site every week, but they don't often seem to grow into avid users (they get stuck at a reputation of 1, or 101 if they have other StackExchange accounts). See https://tridion.stackexchange.com/users?tab=NewUsers&sort=creationdate for the list.
I have a feeling because of the welcome we give (some of) them they end up not caring. Just an example of how new people are welcomed here: https://tridion.stackexchange.com/questions/18121/migrating-from-dd4t-providers-sdltridion2013sp1-to-dd4t-providers-sdlweb8
The user is new to our site and as it seems also new to our product, he (or she) asks a question and gets welcomed with two downvotes. No comments on why his (or her) question is downvoted, just two downvotes. I left a comment asking for an edit on the question (as I often do, after I had seen the first downvote), today I notice a second down vote but nobody is even trying to help this user.
If you ask me downvotes are the most rediculous thing you can ever use, certainly on new users. For one, it won't cost the new user any points since they cannot get a reputation less than 1, but it does cost you as a downvoter 1 point. More importantly if you downvote without leaving a comment, to me that feels like you are stabbing somebody in the back. They are hurt, but have no idea who did it or why it was done.
Downvotes are an important tool to keep our site clean and to the point, it makes sense to downvote a bad question when you know the user who asked the question should know better. But even then, if you decide to downvote, please leave a comment indicating what is wrong with the question, so the user gets a change to edit his question and improve it (after which you can decide to remove your downvote, since the question has been edited).
Let's discuss this...
update
Seems we still have people doing it, see Upgrade to SDL Web 8.5 queries it got a downvote without a comment on it. I'll add the featured tag to this question to see if it can get some more views and a continued discussion.
