BB dynamics are interesting,, the following are general comments, not about this board but about boards in general, I don't know enough about this particular board to comment on it.
Things to watch out for -
ganging up on individuals who disagree. 'Momentum' where emotions get more intense and a story's facts 'drift' the more often it is repeated.
Opinions represented as facts. Typical 'errors of logic' tactics in arguments and debates.
Each board has a culture and a point of view. Disagree at your own peril. Those who agree are popular, others are not.
Rules. Not all are clear. What is acceptable to one person is not to another.
Don't assume you 'know' someone by how they write or what they say on a bb. It is like trying to say what a puzzle is of by looking at one very small piece.
Quite a few posters who are 'long winded' or 'have the last word' may be laid up, or isolated, without a support system or much they can do. Or they may have insomnia. Or that may simply be how they write or edit, and nothing more. Those who seem 'angry' may not be at all. Those who seem 'sweet', conversely, may not be at all. Most of 'what you see' on a bb is going to tell you very, very little about the person.
Don't get too excited by reading something and being 'sure' it's 'true'. You've all heard the jokes about the fat old guy who poses as a rich 21 year old with a red ferarri. There are no guarantees that how a person seems is how they really are or that anything they say is true. There are no 'standards of excellence' on the web.
People always, always have a reason WHY they take a certain position. Learning to respect other people's experience and try to understand HOW they got to their point of view, should be more important than the typical clever sounding bb verbal jousting to see who comes out 'on top'.
Just discarding the information the person presents or saying it's irrelevant might lead to a typical bb problem - brain atrophy. Never ever considering any other point of view's possible merits, leads to people who are limited and rigid in their thinking. Studies indicate people stick to web sites that confirm what they already believe, rather than as a earning or transformative activity.
