Your question essentially describes the differences between the General and Social sections. General is for when the OP (original poster) wants a more direct response to their specific question without an exploration of the subject at large. Social is for when the OP is open to allowing the conversation to develop and unfold. In both sections, the Guidelines indicate the responses must be respectful, related to the discussion, and not disruptive.
This is a Q&A site, and Facebook-like status messages are not appropriate here, @Mimishu1995, nor are blog-like posts. The chat rooms, profile pages and messages are places where people can link to pictures of their kids and pets, enjoy casual conversation with others, and discuss off-topic matters.
As others have noted, each Jelly’s intentions may vary. There are some who like to call attention to themselves, there are some who only want confirmation of their own views and do not handle opposing viewpoints well, there are some who like to find ways to get others riled-up, and there are some who are difficult to understand. While these behaviors are against the rules, there is a tremendous grey-area when in comes to interpretation of the user’s intentions, as there is great variability and no way to please all members of the collective.
If someone sees something questionable within a few minutes after it’s been posted, the Jelly who wrote it can be contacted via private message (accessed from their profile page) and they might be able to edit it within the 10-minute editing window. In some situations, it is fine to ask for clarification of another person’s content within the thread, as long as it is done in a courteous manner.
The flagging system is how the members of the collective can bring questionable content to the attention of the team of moderators, of which I am a member. With blatant violations of the guidelines, such as spam and personal attacks, it is best to flag the content and move on. If one wants to reach the moderation team to discuss a moderation decision, or to call attention to something that can’t be addressed by flagging, there’s the Contact button at the top of the page that goes to the whole team.
