This isn't a question, it's an appeal.
Recently, I've noticed there has been a large increase in the number of good answers being put in the comments of questions, because people are overly cautious of putting forward an answer.
And this is increasing even in spite of an existing post on meta trying to address this problem: Comments are not for Answers.
I feel that is possibly partly because our community is particularly subject to fear of being wrong and hesitation to answer. Let's face it, it's a quirk of Japanese culture that people are hesitant to answer unless they are 100%, rock-solid, totally sure of their answer.
So, I thought it worthwhile to address the issue from another perspective, which is that the green check mark awarded by the questioner should not be viewed as the absolute deciding factor in determing if an answer is "right".
Or, put another way, not getting a green check mark does not mean failure.
This question is a good example. The questioner asks if 一緒に is needed when saying 行こう.
There are two ways of looking at it. One is that grammatically speaking, 一緒に is necessary. Or it's more precise.
However, another way of looking at it is that in day to day conversation, people can and often do drop 一緒に because it's understood from context.
So, we might get two answers. One from the grammatical perspective, and one from the point of view of common use. The questioner might apply the green check to either answer, depending on which was of most interest to that person.
But that doesn't mean the other answer is wrong. Other people might want to know about the other points.
In short, just because a person asks a question doesn't mean they are the final authority on what is right (if they knew what was right, they wouldn't need to ask!). What they apply the green check to is what they are interested in knowing.
For the benefit of the community, multiple answers increase the chance that everyone gets the answer they are looking for.
So... in conclusion, don't hesitate to answer just because it might not be the perfect, complete, and final answer. Lots of answers are good. Even partial answers which address only one aspect of the issue are good.
So stop commenting. Put in answers! :)
Just an additional note:
For this site to get out of beta, questions need to have an average of 2.5 answers.
That shouldn't necessarily taken to mean that there should be a bunch of answers from which the questioner gets to decide which is right. It means there should be multiple perspectives so that other people coming to the site looking for information get complete information.
It increases the value of the site, and valuable sites get to move out of beta.
