While we can't fix these, we can make them less traumatic by keeping them in mind. Therefore, violating the guideline regarding careful consideration of posting becomes very easy to do. Force yourself to stop and consider your posts before you send them. It's impossible to be sure of the true emotional motivations behind others' posts, or their implied emotional content. Therefore, it's best to avoid assumptions about the feelings and motivations of others on the net.
Time lags are inherent in the system.
Some people take longer to get posts than others. When you see a new post which says things you've already responded to, therefore, consider the possibility that the poster has just received an old post of yours. In fact, it is possible that some users may see and respond to a response to a post before ever seeing the original post. This can on occasion result in some bizarre misunderstandings and quotations out of context. Speech debates rely as much on style and poise as on substance of one's arguments.
