We should somehow survey the users to see if their alone-in-a-crowd attitude prevents them from actively posting, and then encourage them to post, because compartmentalization is not a good habit. And I think people who agree that you should help the epileptic however many people are also present, but not that you should speak out 'what is obvious' if there are other users with a history of commenting, compartmentalize.

(OTOH, maybe it's me rationalizing asking much and answering little.)
