The top two answers (at present) said, very well, quite a bit of what I was going to say, so I will leave those points alone for the most part. In that regard, just count me as a voice in agreement with my peers' responses.
First, I do feel that it is very fitting and appropriate for you to see, and have an expectation of using, the Interpersonal Skills site as a tool for...
"...getting used to how people react and what someone might expect from me."
Again, I agree with others who have stated that you could learn a lot and teach a lot, both because a lot of interpersonal skills are common sense and because non-typical advice is just as worthy as what "everyone knows," as long as it suits the stated situation.
Mostly, I wanted to address your two current views of the site. As I interpret (and translate) your post, what you have found here so far has brought you to see the site as either:
- "this page will be about finding ways in respect to ones mentality and/or ethics to find fit into general expectations to interpersonal skills" [...will be a place to learn, with respect to one's mentality and/or ethics, how to fit into general expectations with regard to interpersonal skills]
- "there is just wrong and right, therefor if I dont want to take the right way its implicite the wrong way I'm taking" [according to the answers, there is just wrong and right – if I don't want to take the right way, then the wrong way I'm taking will be impolite.]
In theory, I think the site is pretty much supposed to go along with the first of these impressions. It's fair to say (and fairer still for you to intuit) that answers should consider the OP's mentality and ethics, just as they should take into effect the region (or culture of the region) where the OP is from, and all other background information and extenuating circumstances included in the question. In my opinion, this can definitely include various disability aspects.
As with any tidbit of information that might alter the situation (and thus, the advice), however, the OP should be clear about it in the question, and as clear as possible about how it does or could alter interpersonal relations or, heh, other aspects of reality. Only with everything on the table and all of it spelled out clearly can even the most conscientious adviser hope to give good feedback. [Note: I am not saying that you failed to do this in the question you cite above. Maybe you did and maybe you didn't; right now I'm just talking about the minimum standard of input required on this site to receive the maximum standard of output.]
Your other perception of what this site is or might offer is fairly accurate as well. I mean, we do hope to attract people who can see more than black/white, day/night, wrong/right, and who'll take the time to consider the finer nuances of the question, but ... it's the internet (open to everyone), there's no entry fee (in a general sense, when people don't have to pay to participate, they don't put in as much effort and the quality of output suffers), and a lot of the people in the world today are either too narrow-minded, too impatient, or they don't have the attention span needed to thoroughly think things through.
It is this fact that is behind one of the major flaws of this site: mediocre (or even poor) answers will bury good answers if they resemble the voters' own personal experiences – hello, a good answer is supposed to reflect the OP's situation! Sorry about the run-on sentences and ranting. What I'm saying is that you shouldn't necessarily take answers – even popular ones – as exactly correct for your situation, as a lot of answers don't reflect the intended mission of the site, which is, I suspect, something like this:
Every question will receive the best possible answer from anyone who chooses to leave one; of those, the best answer will rise to the top as the wider community applies great consideration to the question and to every answer before voting.
Please note, there are a lot of great people here doing a lot to keep the place on track. Yet, while there is little we can do to ensure that others apply the standards of that mission, they're not the ones asking if their contribution will be a help here. No, that would be you. That gives me great hope that if you choose to keep that standard in mind, your contributions will be of great help here! And if you will keep in mind that the site has great benefit but is far from perfect, you will probably be able to find some help here, too.
