In general, one should attempt to flesh out questions and arguments in the philosophy forums adequately enough that readers will have a good understanding of the problem, the backdrop against which it resides, and the justification of one's perspective. This might include
* explicitly defining key terms;
* justifying why this is a valid issue or problem in the first place;
* explicitly stating starting premises or assumptions;
* providing logical or empirical support for such premises or assumptions;
* making subtle logical steps more explicit;
* summarizing previous arguments made on the topic and explaining how they are relevant to your argument;
* etc.
