I will give the example of this answer.
It was a bad answer, not much information in it, not really a good work around. A bad answer is a bad answer, we all understand that.
Now, I look at the user that answered that and I see 1 valid question, nothing else. I can assume that this was one of his first answers in the site. Everyone has been there: new to the site, ingenious, maybe a bit shy and not knowing exactly if his information will be in any way received or helpful, and then it gets hit with comments as the ones posted on that answer.
This answer is not helpful or useful at all! explain yourself give us names and links! or just delete the post! read the FAQ!!!
(...)but that answer is so bad that it annoys me a lot...
In my humble and not so important opinion, this way of commenting should be strongly avoided. We are a community that prides it self with good behaviour, help is given and taken, development is done based on that. We are one of the faces of Ubuntu.
If someone needs help or guidance when he himself is trying to help but instead gets whooshed out what kind of example are we?
I was tempted to flag those comments as rude at the time, but being myself also a recent member to the site I have failed on not doing so. I was afraid another user would be punished for something that can be considered rude or for others just harsh.
What is your opinion on flagging comments to moderators, where is the threshold where things go from acceptable to rude, who decides those and will there be any consequences to the person flagged? What if a moderator does not agree, what will happen?
In the end my question is: should we be quicker on flagging rude comments?
