On a site like this, I am very careful because there are people who tend to be more sensitive than on other more general sites (I frequent a very popular movie site and a cooking site). If I feel qualified to answer a question here or help someone, I think about it very carefully because it may have a big impact (it may not, but I'd rather err on the side of caution).
My main goal is to help the person while being honest. I don't need to post to get "published" or get notches on my posting belt, or to appear to be witty or clever by throwing off some pat or glib answer. I don't need to post quickly, it's not a race. I need to post thoughtfully and carefully. If I can't do this, I won't post at all.
I know that I can't expect to change anyone's life positively by what I post or, on the other hand, be responsible for something that a person does negatively by what I post, but I don't want to ever have to question myself about that. I don't see the point in posting something that isn't helpful or that could possibly be negative and hurtful. I know that it's important to put information out there, but I think it's really already out there or rather the negative opinions are out there. Everybody has heard them more than enough. That's why people come here.
