Perhaps why many don't understand, is that what ever an OP write, don't think before they write. They tend to just write what comes in there minds, and say it as they think it, without any thought, "oh errm i may rephrase that or this in case people take me. wrong". So you can see how sometimes how some threads are taken wrong or negative. You cant see emotion behind something that is written.
However, there are those who know's what they are saying or asking, know what ripple or effect it will cause when they put a spanner in the works, in which they enjoy and sit back and what the responses.
