Problem: The real point of a discussion is lost on the casual reader, or

• the reader has to read most of the page to get to its “punchline”, or
• the writing is targeted to particular people you know already know what the discussion is about.

Write for a generic reader: There are 100 readers for every page writer.

• Most visitors to the page will want substance, but won't know necessarily all the peculiarities of a given discussion or topic.
• Write for people who are just visiting.
• Compose and organize your thoughts for the reader's benefit.
