Hi all :)

Idea: When a user with less than 2K reputation clicks the "downvote" button, their downvote should be noted.

Then, the site should pop up a big AJAX dialog box. The dialog box should ask, "How can this post be improved?" and include a big textbox and a "Submit Comment" button.

Thoughts?

bjb568

No

Why does the dialog box have to be ajax?

unforgettableid

@bjb568 It doesn't.

bjb568

Oh good.

unforgettableid

BTW, the downvoter can close the dialog box if they don't want to comment.

bjb568

00:16

Meh. There's already a blue notice.

unforgettableid

@bjb568 not aggressive enough.

bjb568

Why's it need to be aggressive?

Q: How can we discourage over-downvoting on questions?

@bjb568 The blue notice discourages commentless downvoting, but I'm not sure it's enough. A dialog box might be enough.

bjb568

00:19

What's wrong with commentless downvoting?

unforgettableid

@bjb568 It's not wrong per se, but it discourages posters. Better to tell them what they can do better instead.

bjb568

No. They don't listen.

unforgettableid

@bjb568 I listen.

bjb568

@unforgettableid You aren't a low quality user.

I would comment anyway.

unforgettableid

@bjb568 But some others don't.

bjb568

00:22

@unforgettableid So do you think the minimal benefit of some people (waves hands) commenting slightly more when it likely won't help outweighs the change in voting behavior and the extreme annoyance of a pop-up box(!) ?

unforgettableid

@bjb568 (If you comment or edit before you downvote, the box shouldn't pop up. Does your question still stand?)

bjb568

Yes. I want to just DV, CV, VLQ, and be done in 5 seconds (if the post is utter crap, which is quite easy to find and go thru).

user259867

@bjb568 Why VLQ? CV already puts it in the Review queue, there is no extra gain from VLQ other than to annoy some mod.

bjb568

V.L.Q Is. Not. For. Mods.

It's for the LQRQ.

Shogging through the snow

V.L.Q. Is. For. Lovers.

bjb568

And there exist questions which deserve to be in the LQRQ.

@bjb568 what's CV?

bjb568

@unforgettableid Closevote.

user259867

@bjb568 But the only thing reviewers can do with them is... put in the close queue.

bjb568

@Behaviour No, they can close and downvote.

bjb568

You would.

unforgettableid

Another idea.
When you're viewing comments, they could implement a "link my next comment as a reply to this one" button.
When two comments are linked and you hover your mouse over one, the other could get a shaded background.
Thoughts?

bjb568

00:40

@unforgettableid yes

hichris123

@bjb568 If this was any other day, I would have totally flagged you by now.

And Shog would have drank more.

unforgettableid

00:44

@bjb568 what does "yes" mean in this context?

bjb568

@unforgettableid "good idea"

Infinite Recursion

Chat already supports linking messages, so you would end up integrating chat into the comment interface @unforgettableid, I would personally upvote such an FR, but who knows if the community would like it or not.

unforgettableid

@InfiniteRecursion No. Chat and comments should be different.

People shouldn't have 100-line comment conversations.

@InfiniteRecursion Why do you believe that implementing such an idea would integrate chat into the comment interface?

@InfiniteRecursion It would integrate only one aspect of chat, not the whole thing.

Infinite Recursion

Software reusability. If I were the dev, I would reuse the chat module, that's why I thought like that.

You are right, your proposal doesn't imply integration.

What other goals are there?

user259867

Life is good for only two things, writing in markdown and parsing markdown.

unforgettableid

@bjb568 So why not use a pre-existing Markdown parser, instead of writing your own? :)

bjb568

@unforgettableid they sux

unforgettableid

@bjb568 how so?

bjb568

01:33

Complicated, low quality, not trustable, implementing weird parts / too much

Eg commonmark supports HTML.

unforgettableid

@bjb568 I believe that the Markdown spec says that all HTML is allowed in Markdown. Including, as this fellow once said, <script>doEvil();</script>.
