On: Ask HN - I don't understand the up/down arrows behavior ...

[markup]

When it happens to me it is because I have replied to that comment. I assume that it is because if you replied to a comment you DO think it is worth reading it, and it surely contributed to the discussion, therefore no sense in downmodding it

You can't downmod a response to your own comment. That's the only anomaly I've seen.

There is also some sock-puppet detection as well - this is to prevent you creating accounts and upvoting yourself. Presume it also prevents you downmodding every comment by someone you don't like too...

I've seen it occasionally go awry - you'll upvote and the vote just disappears.

As Dasil says you cant down mod replies to your comments (for obvious reasons :D).

I find I can vote on comments I reply to... (it doesnt, to me, appear to be logical that if your replying you agree with the post).

I can't down mod ANY comments. I don't mind, really. I'm a pretty positive guy.

[markup → ErrantX]

Well I cannot downmod comments I have already replied to. Up/downmodding does NOT mean you agree or disagree with that comment, it means you find it useful/interesting or that it has added something/contributed to the discussion

how do you mean by already ?

I can still down mod the comments in this thread that I have replied to.

EDIT: wait NOW I see :) I cant down the above comment. Ignore me :)

[diN0bot → ErrantX]

if you down mod and then reply does the karma get removed?

[ErrantX → diN0bot]

good question.

I volunteer to be downmodded and replied too :)

[jonursenbach → ErrantX]

downmodded and here's your reply.

Well, it looks like I was looking at comments older than 24hrs (can downmod comments I have replied to, in the last few minutes): so I am wrong on this :-)
